Tiny QUnit async test helper, eliminates pyramid code in async tests with multiple assertions, each requiring its own delay.

QUnit.chain

/**
 * testAsyncStepsWithPause
 * Executes any number of async Qunit tests with a pause between each step
 *
 * Author: Matthew O'Riordan, http://mattheworiordan.com
 *
 * Params:
 * @timeToWait: milliseconds between running method and running tests
 * @methods: 1+ function arguments passed in the format:
 *   function() {
 *      // execute code here which requires the tests to wait for @timeToWait
 *      return function() {
 *        // execute assertions here, will be executed after @timeToWait
 *      }
 *   }, ...
