	/**
	 * <code>sap.ui.qunit.utils.ControlIterator</code> is a utility for collecting all available controls across libraries in order to e.g. run tests on each of them.
	 *
	 * It is used by calling the static <code>run</code> function with a callback function as parameter. This function will be called for each control
	 * (and provide control name and class and more information about the control as arguments), so a test could be executed for this control.
	 *
	 * The second parameter of the <code>run</code> function can be used to configure several options, e.g. to define a hard-coded list of control libraries
	 * to test (otherwise all available libraries are discovered), to exclude certain controls or libraries, to state whether sap.ui.core.Elements should
	 * also be tested, etc.
	 * Check the documentation of the <code>run</code> function parameters to understand which Controls/Elements are used by default and which ones are excluded.
	 *
	 * The <code>run</code> function does NOT execute synchronously! In case a QUnit test function is written that embeds a call to <code>run</code>
	 * (as opposed to creating a test function inside each callback), this test function needs to be asynchronous and needs to use the <code>done</code>
	 * callback option (called when all control tests have been executed) to call <code>done()</code> (the function returned by <code>assert.async()</code>).
	 *
	 * Usage example:
	 * <code>
	 * QUnit.config.autostart = false;
	 *
	 * sap.ui.require(["sap/ui/qunit/utils/ControlIterator"], function(ControlIterator) {
	 *
	 *    ControlIterator.run(function(sControlName, oControlClass, oInfo) { // loop over all controls
	 *
	 *       QUnit.test("Testing control " + sControlName, function(assert) { // create one test per control
	 *          assert.ok(true, sControlName + " would be tested now");
	 *          // e.g. create a control instance:  oControl = new oControlClass()
	 *       });
	 *
	 *    },{
	 *       librariesToTest: ["sap.ui.someLibrary"], // optionally limit the test scope or do other settings
	 *       done: function(oResult) {
	 *          // do something when the above function has been executed for all controls (here: all control tests have been created)
	 *
	 *          QUnit.start(); // tell QUnit that all tests have now been created (due to autostart=false)
	 *       }
	 *    });
	 *
	 * });
	 * </code>
	 *
	 * This module is independent from QUnit, so it could be used for other purposes than unit tests.
