*
* config.image2_alignClasses = [ 'align-left', 'align-center', 'align-right' ];
*
* **Note**: Once this configuration option is set, the plugin will no longer produce inline
* styles for alignment. It means that e.g. the following HTML will be produced:
*
* <img alt="My image" class="custom-center-class" src="foo.png" />
*
* instead of:
*
* <img alt="My image" style="float:left" src="foo.png" />
*
* **Note**: Once this configuration option is set, corresponding style definitions
* must be supplied to the editor:
*
* * For [classic editor](#!/guide/dev_framed) it can be done by defining additional
* styles in the {@link CKEDITOR.config#contentsCss stylesheets loaded by the editor}. The same
* styles must be provided on the target page where the content will be loaded.
* * For [inline editor](#!/guide/dev_inline) the styles can be defined directly
* with `<style> ... <style>` or `<link href="..." rel="stylesheet">`, i.e. within the `<head>`
* of the page.
*
* For example, considering the following configuration:
*
* config.image2_alignClasses = [ 'align-left', 'align-center', 'align-right' ];
*
* CSS rules can be defined as follows:
*
* .align-left {
* float: left;
* }
*
* .align-right {
* float: right;
* }
*
* .align-center {
* text-align: center;
* }
*
* .align-center > figure {
* display: inline-block;
* }

* @cfg {String[]} [image2_alignClasses=null]

*
* `sequenceEqual` subscribes to two observables and buffers incoming values from each observable. Whenever either
* observable emits a value, the value is buffered and the buffers are shifted and compared from the bottom
* up; If any value pair doesn't match, the returned observable will emit `false` and complete. If one of the
* observables completes, the operator will wait for the other observable to complete; If the other
* observable emits before completing, the returned observable will emit `false` and complete. If one observable never
* completes or emits after the other complets, the returned observable will never complete.
*
* @example <caption>figure out if the Konami code matches</caption>
* var code = Rx.Observable.from([
* "ArrowUp",

// This depends on tinytest, so it's a little weird to put it in
// test-helpers, but it'll do for now.
// Provides the testAsyncMulti helper, which creates an async test
// (using Tinytest.addAsync) that tracks parallel and sequential
// asynchronous calls. Specifically, the two features it provides
// are:
// 1) Executing an array of functions sequentially when those functions
// contain async calls.
// 2) Keeping track of when callbacks are outstanding, via "expect".
//
// To use, pass an array of functions that take arguments (test, expect).
// (There is no onComplete callback; completion is determined automatically.)
// Expect takes a callback closure and wraps it, returning a new callback closure,
// and making a note that there is a callback oustanding. Pass this returned closure
// to async functions as the callback, and the machinery in the wrapper will
// record the fact that the callback has been called.
//
// A second form of expect takes data arguments to test for.
// Essentially, expect("foo", "bar") is equivalent to:
// expect(function(arg1, arg2) { test.equal([arg1, arg2], ["foo", "bar"]); }).
//
// You cannot "nest" expect or call it from a callback! Even if you have a chain
// of callbacks, you need to call expect at the "top level" (synchronously)
// but the callback you wrap has to be the last/innermost one. This sometimes
// leads to some code contortions and should probably be fixed.
// Example: (at top level of test file)
//
// testAsyncMulti("test name", [
// function(test, expect) {
// ... tests here
// Meteor.defer(expect(function() {
// ... tests here
// }));
//
// call_something_async('foo', 'bar', expect('baz')); // implicit callback
//
// },
// function(test, expect) {
// ... more tests
// }
// ]);

* A BasicSourceMapConsumer instance represents a parsed source map which we can
* query for information about the original file positions by giving it a file
* position in the generated source.
*
* The only parameter is the raw source map (either as a JSON string, or
* already parsed to an object). According to the spec, source maps have the
* following attributes:
*
* - version: Which version of the source map spec this map is following.
* - sources: An array of URLs to the original source files.
* - names: An array of identifiers which can be referrenced by individual mappings.
* - sourceRoot: Optional. The URL root from which all sources are relative.
* - sourcesContent: Optional. An array of contents of the original source files.
* - mappings: A string of base64 VLQs which contain the actual mappings.
* - file: Optional. The generated file this source map is associated with.
*
* Here is an example source map, taken from the source map spec[0]:
*
* {
* version : 3,
* file: "out.js",
* sourceRoot : "",
* sources: ["foo.js", "bar.js"],
* names: ["src", "maps", "are", "fun"],
* mappings: "AA,AB;;ABCDE;"
* }
