// Ids are base 32 strings whose binary representation corresponds to the

//
// 00101 00010001011010101
// ╰─┬─╯ ╰───────┬───────╯
// Fork 5 of 20 Parent id
//
// The leading 0s are important. In the above example, you only need 3 bits to
// represent slot 5. However, you need 5 bits to represent all the forks at
// the current level, so we must account for the empty bits at the end.
//
// For this same reason, slots are 1-indexed instead of 0-indexed. Otherwise,
// the zeroth id at a level would be indistinguishable from its parent.
//
// If a node has only one child, and does not materialize an id (i.e. does not
// contain a useId hook), then we don't need to allocate any space in the
// sequence. It's treated as a transparent indirection. For example, these two
// trees produce the same ids:
//
// <> <>
// <Indirection> <A />
// <A /> <B />
// </Indirection> </>
// <B />
// </>
//
// However, we cannot skip any node that materializes an id. Otherwise, a parent
// id that does not fork would be indistinguishable from its child id. For
// example, this tree does not fork, but the parent and child must have
// different ids.
//
// <Parent>
// <Child />
// </Parent>
//
// To handle this scenario, every time we materialize an id, we allocate a
// new level with a single slot. You can think of this as a fork with only one
// prong, or an array of children with length 1.
//
// It's possible for the size of the sequence to exceed 32 bits, the max
// size for bitwise operations. When this happens, we make more room by
// converting the right part of the id to a string and storing it in an overflow
// variable. We use a base 32 string representation, because 32 is the largest
// power of 2 that is supported by toString(). We want the base to be large so
// that the resulting ids are compact, and we want the base to be a power of 2
// because every log2(base) bits corresponds to a single character, i.e. every
// log2(32) = 5 bits. That means we can lop bits off the end 5 at a time without
// affecting the final result.

// This branch assumes the length of the base id is greater than 5; it won't

// We encode the id in multiple steps: first the base id, then the

//
// Each 5 bit sequence corresponds to a single base 32 character. So for

`fire`d from any object in the YUI instance sandbox</li>

<li>Subscribe to the execution of a method on any object, effectively

and callback as the second. The `this` object in the callback will be `Y` unless
an override is passed as the third argument.
Y.on('io:complete', function () {
Y.MyApp.updateStatus('Transaction complete');

To subscribe to DOM events, pass the name of a DOM event as the first argument
and a CSS selector string as the third argument after the callback function.
Alternately, the third argument can be a `Node`, `NodeList`, `HTMLElement`,
array, or simply omitted (the default is the `window` object).
Y.on('click', function (e) {
e.preventDefault();
// proceed with ajax form submission
var url = this.get('action');
...
}, '#my-form');
The `this` object in DOM event callbacks will be the `Node` targeted by the CSS
selector or other identifier.
`on()` subscribers for DOM events or custom events `publish`ed with a
`defaultFn` can prevent the default behavior with `e.preventDefault()` from the
event object passed as the first parameter to the subscription callback.
To subscribe to the execution of an object method, pass arguments corresponding to the call signature for
<a href="../classes/Do.html#methods_before">`Y.Do.before(...)`</a>.

/**
* Summary of `ReactBrowserEventEmitter` event handling:
*
* - Top-level delegation is used to trap most native browser events. This
* may only occur in the main thread and is the responsibility of
* ReactEventListener, which is injected and can therefore support pluggable
* event sources. This is the only work that occurs in the main thread.
*
* - We normalize and de-duplicate events to account for browser quirks. This
* may be done in the worker thread.
*
* - Forward these native events (with the associated top-level type used to
* trap it) to `EventPluginHub`, which in turn will ask plugins if they want
* to extract any synthetic events.
*
* - The `EventPluginHub` will then process each event by annotating them with
* "dispatches", a sequence of listeners and IDs that care about that event.
*
* - The `EventPluginHub` then dispatches the events.
*

Columns to include in the rendered table.
If omitted, the attributes on the configured `recordType` or the first item
in the `data` collection will be used as a source.
This attribute takes an array of strings or objects (mixing the two is
fine). Each string or object is considered a column to be rendered.
Strings are converted to objects, so `columns: ['first', 'last']` becomes
`columns: [{ key: 'first' }, { key: 'last' }]`.
DataTable.Core only concerns itself with a few properties of columns.
These properties are:
* `key` - Used to identify the record field/attribute containing content for
this column. Also used to create a default Model if no `recordType` or
`data` are provided during construction. If `name` is not specified, this
is assigned to the `_id` property (with added incrementer if the key is
used by multiple columns).
* `children` - Traversed to initialize nested column objects
* `name` - Used in place of, or in addition to, the `key`. Useful for
columns that aren't bound to a field/attribute in the record data. This
is assigned to the `_id` property.
* `id` - For backward compatibility. Implementers can specify the id of
the header cell. This should be avoided, if possible, to avoid the
potential for creating DOM elements with duplicate IDs.
* `field` - For backward compatibility. Implementers should use `name`.
* `_id` - Assigned unique-within-this-instance id for a column. By order
of preference, assumes the value of `name`, `key`, `id`, or `_yuid`.
This is used by the rendering views as well as feature module
as a means to identify a specific column without ambiguity (such as
multiple columns using the same `key`.
* `_yuid` - Guid stamp assigned to the column object.
* `_parent` - Assigned to all child columns, referencing their parent
column.

1. If the `data` attribute is set with a ModelList instance and its `model`

2. If the `data` attribute is set with a ModelList instance, and its
`model` property is unset, but it is populated, the `ATTRS` of the
`constructor of the first item will be used.
3. If the `data` attribute is set with a non-empty array, a Model subclass
will be generated using the keys of the first item as its `ATTRS` (see
the `_createRecordClass` method).
4. If the `columns` attribute is set, a Model subclass will be generated
using the columns defined with a `key`. This is least desirable because
columns can be duplicated or nested in a way that's not parsable.
5. If neither `data` nor `columns` is set or populated, a change event
