/**
 * Function: Stub
 *
 * The Stub object is used to create stubs or mocks during tests. In addition to
 * running the function that's returned, the returned function contains the
 * properties 'called', 'numCalled' and 'origFunc'
 *
 *   var myStub = new Stub(function(param) {
 *     // do stuff
 *     return param;
 *   });
 *
 *   var foo = myStub('bar');
 *
 *   myStub.called;
 *   // ... true
 *   myStub.numCalled;
 *   // ... 1
 *   myStub.originalFunc;
 *   // ... [Function]
 *
 * Parameters:
 *
 *   function - the actual function for the stub to call
 *
 * Returns:
 *
 *   returns output from the function passed as parameter
