/**
* Custom gestures
* ==============================
*
* Gesture object
* --------------------
* The object structure of a gesture:
*
* { name: 'mygesture',
* index: 1337,
* defaults: {
* mygesture_option: true
* }
* handler: function(type, ev, inst) {
* // trigger gesture event
* inst.trigger(this.name, ev);
* }
* }
* @param {String} name
* this should be the name of the gesture, lowercase
* it is also being used to disable/enable the gesture per instance config.
*
* @param {Number} [index=1000]
* the index of the gesture, where it is going to be in the stack of gestures detection
* like when you build an gesture that depends on the drag gesture, it is a good
* idea to place it after the index of the drag gesture.
*
* @param {Object} [defaults={}]
* the default settings of the gesture. these are added to the instance settings,
* and can be overruled per instance. you can also add the name of the gesture,
* but this is also added by default (and set to true).
*
* @param {Function} handler
* this handles the gesture detection of your custom gesture and receives the
* following arguments:
*
* @param {Object} eventData
* event data containing the following properties:
* timeStamp {Number} time the event occurred
* target {HTMLElement} target element
* touches {Array} touches (fingers, pointers, mouse) on the screen
* pointerType {String} kind of pointer that was used. matches Hammer.POINTER_MOUSE|TOUCH
* center {Object} center position of the touches. contains pageX and pageY
* deltaTime {Number} the total time of the touches in the screen
* deltaX {Number} the delta on x axis we haved moved
* deltaY {Number} the delta on y axis we haved moved
* velocityX {Number} the velocity on the x
* velocityY {Number} the velocity on y
* angle {Number} the angle we are moving
* direction {String} the direction we are moving. matches Hammer.DIRECTION_UP|DOWN|LEFT|RIGHT
* distance {Number} the distance we haved moved
* scale {Number} scaling of the touches, needs 2 touches
* rotation {Number} rotation of the touches, needs 2 touches *
* eventType {String} matches Hammer.EVENT_START|MOVE|END
* srcEvent {Object} the source event, like TouchStart or MouseDown *
* startEvent {Object} contains the same properties as above,
* but from the first touch. this is used to calculate
* distances, deltaTime, scaling etc
*
* @param {Hammer.Instance} inst
* the instance we are doing the detection for. you can get the options from
* the inst.options object and trigger the gesture event by calling inst.trigger
*
*
* Handle gestures
* --------------------
* inside the handler you can get/set Hammer.detection.current. This is the current
* detection session. It has the following properties
* @param {String} name
* contains the name of the gesture we have detected. it has not a real function,
* only to check in other gestures if something is detected.
* like in the drag gesture we set it to 'drag' and in the swipe gesture we can
* check if the current gesture is 'drag' by accessing Hammer.detection.current.name
*
* @readonly
* @param {Hammer.Instance} inst
* the instance we do the detection for
*
* @readonly
* @param {Object} startEvent
* contains the properties of the first gesture detection in this session.
* Used for calculations about timing, distance, etc.
*
* @readonly
* @param {Object} lastEvent
* contains all the properties of the last gesture detect in this session.
*
* after the gesture detection session has been completed (user has released the screen)
* the Hammer.detection.current object is copied into Hammer.detection.previous,
* this is usefull for gestures like doubletap, where you need to know if the
* previous gesture was a tap
*
* options that have been set by the instance can be received by calling inst.options
*
* You can trigger a gesture event by calling inst.trigger("mygesture", event).
* The first param is the name of your gesture, the second the event argument
*
*
* Register gestures
* --------------------
* When an gesture is added to the Hammer.gestures object, it is auto registered
* at the setup of the first Hammer instance. You can also call Hammer.detection.register
* manually and pass your gesture object as a param

// a transform stream is a readable/writable stream where you do
// something with the data. Sometimes it's called a "filter",
// but that's not a great name for it, since that implies a thing where
// some bits pass through, and others are simply ignored. (That would
// be a valid example of a transform, of course.)
//
// While the output is causally related to the input, it's not a
// necessarily symmetric or synchronous transformation. For example,
// a zlib stream might take multiple plain-text writes(), and then
// emit a single compressed chunk some time in the future.
//
// Here's how this works:
//
// The Transform stream has all the aspects of the readable and writable
// stream classes. When you write(chunk), that calls _write(chunk,cb)
// internally, and returns false if there's a lot of pending writes
// buffered up. When you call read(), that calls _read(n) until
// there's enough pending readable data buffered up.
//
// In a transform stream, the written data is placed in a buffer. When
// _read(n) is called, it transforms the queued up data, calling the
// buffered _write cb's as it consumes chunks. If consuming a single
// written chunk would result in multiple output chunks, then the first
// outputted bit calls the readcb, and subsequent chunks just go into
// the read buffer, and will cause it to emit 'readable' if necessary.
//
// This way, back-pressure is actually determined by the reading side,
// since _read has to be called to start processing a new chunk. However,
// a pathological inflate type of transform can cause excessive buffering
// here. For example, imagine a stream where every byte of input is
// interpreted as an integer from 0-255, and then results in that many
// bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in
// 1kb of data being output. In this case, you could write a very small
// amount of input, and end up with a very large amount of output. In
// such a pathological inflating mechanism, there'd be no way to tell
// the system to stop doing the transform. A single 4MB write could
// cause the system to run out of memory.
//
// However, even in such a pathological case, only a single written chunk
// would be consumed, and then the rest would wait (un-transformed) until
// the results of the previous transformed chunk were consumed.

*
* The signature that <code>on</code> accepts varies depending on the type

* service a specific request for additional information about subscribing
* to that type of event.
*
* <ul>
* <li>Custom events. These events are defined by various

* <li>The type of the event</li>
* <li>The callback to execute</li>
* <li>An optional context object</li>
* <li>0..n additional arguments to supply the callback.</li>
* </ul>
* Example:
* <code>Y.on('domready', function() { // start work });</code>
* </li>
* <li>DOM events. These are moments reported by the browser related
* to browser functionality and user interaction.
* This type of event is delegated to <code>Event</code>'s
* <code>attach</code> method.
* <ul>
* <li>The type of the event</li>
* <li>The callback to execute</li>
* <li>The specification for the Node(s) to attach the listener
* to. This can be a selector, collections, or Node/Element
* refereces.</li>
* <li>An optional context object</li>
* <li>0..n additional arguments to supply the callback.</li>
* </ul>
* Example:
* <code>Y.on('click', function(e) { // something was clicked }, '#someelement');</code>
* </li>
* <li>Function events. These events can be used to react before or after a
* function is executed. This type of event is delegated to <code>Event.Do</code>'s
* <code>before</code> method.
* <ul>
* <li>The callback to execute</li>
* <li>The object that has the function that will be listened for.</li>
* <li>The name of the function to listen for.</li>
* <li>An optional context object</li>
* <li>0..n additional arguments to supply the callback.</li>
* </ul>
* Example <code>Y.on(function(arg1, arg2, etc) { // obj.methodname was executed }, obj 'methodname');</code>
* </li>
* </ul>
*
* <code>on</code> corresponds to the moment before any default behavior of
* the event. <code>after</code> works the same way, but these listeners

/**
* This script publishes a new version of react-native to NPM.
* It is supposed to run in CI environment, not on a developer's machine.
*
* To make it easier for developers it uses some logic to identify with which version to publish the package.
*
* To cut a branch (and release RC):
* - Developer: `git checkout -b 0.XY-stable`
* - Developer: `git tag v0.XY.0-rc` and `git push --tags` to git@github.com:facebook/react-native.git
* - CI: test and deploy to npm (run this script) with version 0.XY.0-rc with tag "next"
*
* To update RC release:
* - Developer: `git checkout 0.XY-stable`
* - Developer: cherry-pick whatever changes needed
* - Developer: `git tag v0.XY.0-rc1` and `git push --tags` to git@github.com:facebook/react-native.git
* - CI: test and deploy to npm (run this script) with version 0.XY.0-rc1 with tag "next"
*
* To publish a release:
* - Developer: `git checkout 0.XY-stable`
* - Developer: cherry-pick whatever changes needed
* - Developer: `git tag latest`
* - Developer: `git tag v0.XY.0`
* - Developer: `git push --tags` to git@github.com:facebook/react-native.git
* - CI: test and deploy to npm (run this script) with version 0.XY.0 with and not tag (latest is implied by npm)
*
* To patch old release:
* - Developer: `git checkout 0.XY-stable`
* - Developer: cherry-pick whatever changes needed
* - Developer: `git tag v0.XY.Z`
* - Developer: `git push` to git@github.com:facebook/react-native.git (or merge as pull request)
* - CI: test and deploy to npm (run this script) with version 0.XY.Z with no tag, npm will not mark it as latest if
* there is a version higher than XY
*
* Important tags:
* If tag v0.XY.0-rcZ is present on the commit then publish to npm with version 0.XY.0-rcZ and tag next
* If tag v0.XY.Z is present on the commit then publish to npm with version 0.XY.Z and no tag (npm will consider it latest)
