/**
* Polls a given function waiting for the given value.
*
* @param object options
*        Options object with the following properties:
*        - validator
*        A validator function that should return the expected value. This is
*        called every few milliseconds to check if the result is the expected
*        one. When the returned result is the expected one, then the |success|
*        function is called and polling stops. If |validator| never returns
*        the expected value, then polling timeouts after several tries and
*        a failure is recorded - the given |failure| function is invoked.
*        - success
*        A function called when the validator function returns the expected
*        value.
*        - failure
*        A function called if the validator function timeouts - fails to return
*        the expected value in the given time.
*        - name
*        Name of test. This is used to generate the success and failure
*        messages.
*        - timeout
*        Timeout for validator function, in milliseconds. Default is 5000 ms.
*        - value
*        The expected value. If this option is omitted then the |validator|
*        function must return a trueish value.
*        Each of the provided callback functions will receive two arguments:
*        the |options| object and the last value returned by |validator|.
