/*
 * This example shows using multiple stop watches in the same program.
 * If we want to use multiple watches, we must provide unique name all of them.
 * 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.
