/**
 * This plugin handles i18n! prefixed modules. It does the following:
 *
 * 1) A regular module can have a dependency on an i18n bundle, but the regular
 * module does not want to specify what locale to load. So it just specifies
 * the top-level bundle, like "i18n!nls/colors".
 *
 * This plugin will load the i18n bundle at nls/colors, see that it is a root/master
 * bundle since it does not have a locale in its name. It will then try to find
 * the best match locale available in that master bundle, then request all the
 * locale pieces for that best match locale. For instance, if the locale is "en-us",
 * then the plugin will ask for the "en-us", "en" and "root" bundles to be loaded
 * (but only if they are specified on the master bundle).
 *
 * Once all the bundles for the locale pieces load, then it mixes in all those
 * locale pieces into each other, then finally sets the context.defined value
 * for the nls/colors bundle to be that mixed in locale.
 *
 * 2) A regular module specifies a specific locale to load. For instance,
 * i18n!nls/fr-fr/colors. In this case, the plugin needs to load the master bundle
 * first, at nls/colors, then figure out what the best match locale is for fr-fr,
 * since maybe only fr or just root is defined for that locale. Once that best
 * fit is found, all of its locale pieces need to have their bundles loaded.
 *
 * Once all the bundles for the locale pieces load, then it mixes in all those
 * locale pieces into each other, then finally sets the context.defined value
 * for the nls/fr-fr/colors bundle to be that mixed in locale.

	 * @param {Function} [options.hrefCallback] if specified, this callback is used to retrieve
	 *  a URL that can be used as the location for a command represented as a hyperlink.  The callback should return 
	 *  the URL.  In this release, the callback may also return a deferred that will eventually return the URL, but this

	 *  Optional.

	 * @param {String} [options.selectionClass] a CSS class name to be appended when the command button is selected. Optional.
	 * @param {String} [options.spriteClass] an additional CSS class name that can be used to specify a sprite background image.  This
	 *  useful with some sprite generation tools, where imageClass specifies the location in a sprite, and spriteClass describes the
	 *  sprite itself.  Optional.
	 * @param {Function} [options.visibleWhen] A callback that returns a boolean to indicate whether the command should be visible
	 *  given a particular set of items that are selected.  Optional, defaults to always visible.
	 * @param {orion.commands.ParametersDescription} [options.parameters] A description of parameters that should be collected before invoking
	 *  the command.

	 *  of an image if no image is supplied.  Optional.
	 * @class A command is an object that describes an action a user can perform, as well as when and

	 * <p>Because the syntax and encoding rules of URIs can be complex, URITemplates are recommended over manual construction of URIs through

	 * <p>The <dfn>template string</dfn> is an expression following a well-defined syntax (see <a href="http://tools.ietf.org/html/rfc6570#section-1.2">here</a>
	 * for an introduction). Most notably, the template may include variables.</p>
	 * <p>Once created, a URITemplate's {@link #expand} method can be invoked to generate a URI. Arguments to {@link #expand} give the values to be 
	 * substituted for the template variables.</p>
	 * @description Creates a new URITemplate.
	 * @param {String} template The template string. Refer to <a href="http://tools.ietf.org/html/rfc6570#section-2">RFC 6570</a> for details
