* - `altclass` (string): If a file type is unsupported, the end-user will
* see the alt text (above) linked directly to the content. That link
* will have this value as its class name. Defaults to blank.
* - `audio` (string): This is an image that should be used as a
* placeholder for audio files before they're loaded (QuickTime-only).
* Can be any relative or absolute URL. Defaults to blank.
* - `bgcolor` (string): The background color for the media, if not
* already transparent. Defaults to `#ffffff`.
* - `height` (integer): The height of the embedded media. Accepts any
* numeric pixel value (such as `360`) or `auto`. Defaults to `auto`,
* and it is recommended that you use this default.
* - `loop` (boolean): Do you want the media to loop when its done?
* Defaults to `false`.
* - `mediaplayer` (string): The location of the included
* `mediaplayer.swf` file. This allows for the playback of Flash Video
* (`.flv`) files, and is the default handler for non-Odeo MP3's.
* Defaults to blank.
* - `video` (string): This is an image that should be used as a
* placeholder for video files before they're loaded (QuickTime-only).
* Can be any relative or absolute URL. Defaults to blank.
* - `width` (integer): The width of the embedded media. Accepts any
* numeric pixel value (such as `480`) or `auto`. Defaults to `auto`,
* and it is recommended that you use this default.
* - `widescreen` (boolean): Is the enclosure widescreen or standard?
* This applies only to video enclosures, and will automatically resize
* the content appropriately. Defaults to `false`, implying 4:3 mode.
*
* Note: Non-widescreen (4:3) mode with `width` and `height` set to `auto`
* will default to 480x360 video resolution. Widescreen (16:9) mode with
* `width` and `height` set to `auto` will default to 480x270 video resolution.

* Converts to and from JSON format.
*
* JSON (JavaScript Object Notation) is a lightweight data-interchange
* format. It is easy for humans to read and write. It is easy for machines
* to parse and generate. It is based on a subset of the JavaScript
* Programming Language, Standard ECMA-262 3rd Edition - December 1999.
* This feature can also be found in Python. JSON is a text format that is
* completely language independent but uses conventions that are familiar
* to programmers of the C-family of languages, including C, C++, C#, Java,
* JavaScript, Perl, TCL, and many others. These properties make JSON an
* ideal data-interchange language.
*
* This package provides a simple encoder and decoder for JSON notation. It
* is intended for use with client-side Javascript applications that make
* use of HTTPRequest to perform server communication functions - data can
* be encoded into JSON notation for use in a client-side javascript, or
* decoded from incoming Javascript requests. JSON format is native to
* Javascript, and can be directly eval()'ed with no further parsing
* overhead
*
* All strings should be in ASCII or UTF-8 format!

* Canonical API to handle WordPress Redirecting

* @package WordPress
* @since 2.3.0
*/
/**
* Redirects incoming links to the proper URL based on the site url.
*
* Search engines consider www.somedomain.com and somedomain.com to be two
* different URLs when they both go to the same location. This SEO enhancement
* prevents penalty for duplicate content by redirecting all incoming links to
* one or the other.
*
* Prevents redirection for feeds, trackbacks, searches, comment popup, and
* admin URLs. Does not redirect on non-pretty-permalink-supporting IIS 7,
* page/post previews, WP admin, Trackbacks, robots.txt, searches, or on POST
* requests.
*
* Will also attempt to find the correct link when a user enters a URL that does
* not exist based on exact WordPress query. Will instead try to parse the URL
* or query in an attempt to figure the correct page to go to.
*
* @since 2.3.0
* @uses $wp_rewrite
* @uses $is_IIS
*
* @param string $requested_url Optional. The URL that was requested, used to
* figure if redirect is needed.
* @param bool $do_redirect Optional. Redirect to the new URL.
* @return null|false|string Null, if redirect not needed. False, if redirect
* not needed or the string of the URL

* Retrieve all children of the post parent ID.
*
* Normally, without any enhancements, the children would apply to pages. In the

* share the same table, so therefore the functionality could apply to any one
* of them. It is then noted that while this function does not work on posts, it
* does not mean that it won't work on posts. It is recommended that you know
* what context you wish to retrieve the children of.
*
* Attachments may also be made the child of a post, so if that is an accurate
* statement (which needs to be verified), it would then be possible to get
* all of the attachments for a post. Attachments have since changed since
* version 2.5, so this is most likely unaccurate, but serves generally as an
* example of what is possible.
*
* The arguments listed as defaults are for this function and also of the
* {@link get_posts()} function. The arguments are combined with the
* get_children defaults and are then passed to the {@link get_posts()}
* function, which accepts additional arguments. You can replace the defaults in
* this function, listed below and the additional arguments listed in the
* {@link get_posts()} function.
*
* The 'post_parent' is the most important argument and important attention
* needs to be paid to the $args parameter. If you pass either an object or an
* integer (number), then just the 'post_parent' is grabbed and everything else
* is lost. If you don't specify any arguments, then it is assumed that you are
* in The Loop and the post parent will be grabbed for from the current post.
*
* The 'post_parent' argument is the ID to get the children. The 'numberposts'
* is the amount of posts to retrieve that has a default of '-1', which is
* used to get all of the posts. Giving a number higher than 0 will only
* retrieve that amount of posts.
*
* The 'post_type' and 'post_status' arguments can be used to choose what
* criteria of posts to retrieve. The 'post_type' can be anything, but WordPress
* post types are 'post', 'pages', and 'attachments'. The 'post_status'
* argument will accept any post status within the write administration panels.
*
* @see get_posts() Has additional arguments that can be replaced.
* @internal Claims made in the long description might be inaccurate.
*
* @since 2.0.0
*
* @param mixed $args Optional. User defined arguments for replacing the defaults.
* @param string $output Optional. Constant for return type, either OBJECT (default), ARRAY_A, ARRAY_N.

/**
* Builds an object with all post type capabilities out of a post type object
*
* Post type capabilities use the 'capability_type' argument as a base, if the
* capability is not set in the 'capabilities' argument array or if the
* 'capabilities' argument is not supplied.
*
* The capability_type argument can optionally be registered as an array, with
* the first value being singular and the second plural, e.g. array('story, 'stories')
* Otherwise, an 's' will be added to the value for the plural form. After
* registration, capability_type will always be a string of the singular value.
*
* By default, seven keys are accepted as part of the capabilities array:
*
* - edit_post, read_post, and delete_post are meta capabilities, which are then
* generally mapped to corresponding primitive capabilities depending on the
* context, which would be the post being edited/read/deleted and the user or
* role being checked. Thus these capabilities would generally not be granted
* directly to users or roles.
*
* - edit_posts - Controls whether objects of this post type can be edited.
* - edit_others_posts - Controls whether objects of this type owned by other users
* can be edited. If the post type does not support an author, then this will
* behave like edit_posts.
* - publish_posts - Controls publishing objects of this post type.
* - read_private_posts - Controls whether private objects can be read.
*
* These four primitive capabilities are checked in core in various locations.
* There are also seven other primitive capabilities which are not referenced
* directly in core, except in map_meta_cap(), which takes the three aforementioned
* meta capabilities and translates them into one or more primitive capabilities
* that must then be checked against the user or role, depending on the context.
*
* - read - Controls whether objects of this post type can be read.
* - delete_posts - Controls whether objects of this post type can be deleted.
* - delete_private_posts - Controls whether private objects can be deleted.
* - delete_published_posts - Controls whether published objects can be deleted.
* - delete_others_posts - Controls whether objects owned by other users can be

WordPress-style Buttons
=======================
Create a button by adding the `.button` class to an element. For backwards
compatibility, we support several other classes (such as `.button-secondary`),
but these will *not* work with the stackable classes described below.
Button Styles
-------------
To display a primary button style, add the `.button-primary` class to a button.
Button Sizes
------------
Adjust a button's size by adding the `.button-large` or `.button-small` class.
Button States
-------------
Lock the state of a button by adding the name of the pseudoclass as
an actual class (e.g. `.hover` for `:hover`).

2.0 - Default Button Style

* using http_build_query().
*
* The only URI that are supported in the HTTP Transport implementation are the HTTP and HTTPS
* protocols. HTTP and HTTPS are assumed so the server might not know how to handle the send
* headers. Other protocols are unsupported and most likely will fail.
*
* The defaults are 'method', 'timeout', 'redirection', 'httpversion', 'blocking' and
* 'user-agent'.
*
* Accepted 'method' values are 'GET', 'POST', and 'HEAD', some transports technically allow
* others, but should not be assumed. The 'timeout' is used to sent how long the connection
* should stay open before failing when no response. 'redirection' is used to track how many
* redirects were taken and used to sent the amount for other transports, but not all transports
* accept setting that value.
*
* The 'httpversion' option is used to sent the HTTP version and accepted values are '1.0', and
* '1.1' and should be a string. Version 1.1 is not supported, because of chunk response. The
* 'user-agent' option is the user-agent and is used to replace the default user-agent, which is
* 'WordPress/WP_Version', where WP_Version is the value from $wp_version.
*
* 'blocking' is the default, which is used to tell the transport, whether it should halt PHP
* while it performs the request or continue regardless. Actually, that isn't entirely correct.
* Blocking mode really just means whether the fread should just pull what it can whenever it
* gets bytes or if it should wait until it has enough in the buffer to read or finishes reading
* the entire content. It doesn't actually always mean that PHP will continue going after making
* the request.

* constants.
*
* Please note that only BASIC authentication is supported by most transports.
* cURL MAY support more methods (such as NTLM authentication) depending on your environment.
*
* The constants are as follows:
* <ol>
* <li>WP_PROXY_HOST - Enable proxy support and host for connecting.</li>
* <li>WP_PROXY_PORT - Proxy port for connection. No default, must be defined.</li>
* <li>WP_PROXY_USERNAME - Proxy username, if it requires authentication.</li>
* <li>WP_PROXY_PASSWORD - Proxy password, if it requires authentication.</li>
* <li>WP_PROXY_BYPASS_HOSTS - Will prevent the hosts in this list from going through the proxy.
* You do not need to have localhost and the blog host in this list, because they will not be passed
* through the proxy. The list should be presented in a comma separated list, wildcards using * are supported, eg. *.wordpress.org</li>
* </ol>
*
* An example can be as seen below.
* <code>
* define('WP_PROXY_HOST', '192.168.84.101');

/**
* Hooks a function or method to a specific filter action.
*
* Filters are the hooks that WordPress launches to modify text of various types
* before adding it to the database or sending it to the browser screen. Plugins
* can specify that one or more of its PHP functions is executed to
* modify specific types of text at these times, using the Filter API.
*
* To use the API, the following code should be used to bind a callback to the
* filter.
*
* <code>
* function example_hook($example) { echo $example; }
* add_filter('example_filter', 'example_hook');
* </code>
*
* In WordPress 1.5.1+, hooked functions can take extra arguments that are set
* when the matching do_action() or apply_filters() call is run. The
* $accepted_args allow for calling functions only when the number of args
* match. Hooked functions can take extra arguments that are set when the
* matching do_action() or apply_filters() call is run. For example, the action
* comment_id_not_found will pass any functions that hook onto it the ID of the
* requested comment.
*
* <strong>Note:</strong> the function will return true no matter if the
* function was hooked fails or not. There are no checks for whether the
* function exists beforehand and no checks to whether the <tt>$function_to_add
* is even a string. It is up to you to take care and this is done for
* optimization purposes, so everything is as quick as possible.

*
* @param string $tag The name of the filter to hook the $function_to_add to.
