	//		dojo/has
	// summary:
	//		Defines the has.js API and several feature tests used by dojo.
	// description:
	//		This module defines the has API as described by the project has.js with the following additional features:
	//
	//		- the has test cache is exposed at has.cache.
	//		- the method has.add includes a forth parameter that controls whether or not existing tests are replaced
	//		- the loader's has cache may be optionally copied into this module's has cahce.
	//
	//		This module adopted from https://github.com/phiggins42/has.js; thanks has.js team!

	// try to pull the has implementation from the loader; both the dojo loader and bdLoad provide one
	// if using a foreign loader, then the has cache may be initialized via the config object for this module
	// WARNING: if a foreign loader defines require.has to be something other than the has.js API, then this implementation fail

			//		 A test function to register. If a function, queued for testing until actually
			//		 needed. The test function should return a boolean indicating

			// now: Boolean?
			//		 Optional. Omit if `test` is not a function. Provides a way to immediately
			//		 run the test and cache the result.
			// force: Boolean?
			//	 	Optional. If the test already exists and force is truthy, then the existing
			//	 	test will be replaced; otherwise, add does not replace an existing test (that

			// example:
			//		A redundant test, testFn with immediate execution:
			//	|	has.add("javascript", function(){ return true; }, true);

			//		Again with the redundantness. You can do this in your tests, but we should
			//		not be doing this in any internal has.js tests
