-   * An extension of the "same-value" algorithm as [described for use by ES6 Map
-   * and Set](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Map#Key_equality)
-   *
-   * NaN is considered the same as NaN, however -0 and 0 are considered the same
-   * value, which is different from the algorithm described by
-   * [`Object.is`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/is).
-   *
-   * This is extended further to allow Objects to describe the values they
-   * represent, by way of `valueOf` or `equals` (and `hashCode`).
-   *
-   * Note: because of this extension, the key equality of Immutable.Map and the
-   * value equality of Immutable.Set will differ from ES6 Map and Set.
-   *
-   * ### Defining custom values
-   *
-   * The easiest way to describe the value an object represents is by implementing
-   * `valueOf`. For example, `Date` represents a value by returning a unix
-   * timestamp for `valueOf`:
-   *
-   *     var date1 = new Date(1234567890000); // Fri Feb 13 2009 ...
-   *     var date2 = new Date(1234567890000);
-   *     date1.valueOf(); // 1234567890000
-   *     assert( date1 !== date2 );
-   *     assert( Immutable.is( date1, date2 ) );
-   *
-   * Note: overriding `valueOf` may have other implications if you use this object
-   * where JavaScript expects a primitive, such as implicit string coercion.
-   *
-   * For more complex types, especially collections, implementing `valueOf` may
-   * not be performant. An alternative is to implement `equals` and `hashCode`.
-   *
-   * `equals` takes another object, presumably of similar type, and returns true
-   * if the it is equal. Equality is symmetrical, so the same result should be
-   * returned if this and the argument are flipped.
-   *
-   *     assert( a.equals(b) === b.equals(a) );
-   *
-   * `hashCode` returns a 32bit integer number representing the object which will
-   * be used to determine how to store the value object in a Map or Set. You must
-   * provide both or neither methods, one must not exist without the other.
-   *
-   * Also, an important relationship between these methods must be upheld: if two
-   * values are equal, they *must* return the same hashCode. If the values are not
-   * equal, they might have the same hashCode; this is called a hash collision,
-   * and while undesirable for performance reasons, it is acceptable.
-   *
-   *     if (a.equals(b)) {
-   *       assert( a.hashCode() === b.hashCode() );
-   *     }
-   *
-   * All Immutable collections implement `equals` and `hashCode`.

-     * Creates a `lodash` object which wraps `value` to enable implicit method
-     * chain sequences. Methods that operate on and return arrays, collections,
-     * and functions can be chained together. Methods that retrieve a single value
-     * or may return a primitive value will automatically end the chain sequence
-     * and return the unwrapped value. Otherwise, the value must be unwrapped
-     * with `_#value`.
-     *
-     * Explicit chain sequences, which must be unwrapped with `_#value`, may be

-     * The execution of chained methods is lazy, that is, it's deferred until

-     *
-     * Lazy evaluation allows several methods to support shortcut fusion.
-     * Shortcut fusion is an optimization to merge iteratee calls; this avoids
-     * the creation of intermediate arrays and can greatly reduce the number of
-     * iteratee executions. Sections of a chain sequence qualify for shortcut
-     * fusion if the section is applied to an array of at least `200` elements
-     * and any iteratees accept only one argument. The heuristic for whether a
-     * section qualifies for shortcut fusion is subject to change.

-/**
- * 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.
- *

-// 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.
