/**
 * Run a new test with the given +title+ and function body, which will
 * be executed within the proper test declarations for the UIAutomation
 * framework. The given function will be handed a +UIATarget+ and
 * a +UIApplication+ object which it can use to exercise and validate your
 * application.
 *
 * The +options+ parameter is an optional object/hash thingie that 
 * supports the following:
 *    logTree -- a boolean to log the element tree when the test fails (default 'true')
 *
 * Example:
 * test("Sign-In", function(target, application) {
 *   // exercise and validate your application.
 * });
 *
