* Once watch is started, we can call `pause` method to pause the watch.
* If watch is paused, we can start it again to start timer. In that case, time will be added to timer.

* Steps involved are:
* - Add watches by any of following methods
* - Call `addWatch` multiple times, with name of watch as parameter, or
* - Call `addWatches` and pass an array of name of watches as parameter.
* - Further operation is same as in `simplewatch` and `pauseDemo` example. However this time, we need to pass
* watch name to all the methods.
