		//	summary:
		//		This plugin provides three dropdowns for setting font information in the editor
		//
		//	description:
		//		The commands provided by this plugin are:
		//
		//		* fontName
		//	|		Provides a dropdown to select from a list of generic font names
		//		* fontSize
		//	|		Provides a dropdown to select from a list of pre-defined font sizes
		//		* formatBlock
		//	|		Provides a dropdown to select from a list of styles
		//  |
		//
		//		which can easily be added to an editor by including one or more of the above commands
		//		in the `plugins` attribute as follows:
		//
		//	|	plugins="['fontName','fontSize',...]"
		//
		//		It is possible to override the default dropdown list by providing an Array for the `custom` property when
		//		instantiating this plugin, e.g.
		//
		//	|	plugins="[{name:'dijit._editor.plugins.FontChoice', command:'fontName', custom:['Verdana','Myriad','Garamond']},...]"
		//
		//		Alternatively, for `fontName` only, `generic:true` may be specified to provide a dropdown with
		//		[CSS generic font families](http://www.w3.org/TR/REC-CSS2/fonts.html#generic-font-families)
		//
		//		Note that the editor is often unable to properly handle font styling information defined outside
		//		the context of the current editor instance, such as pre-populated HTML.
