 * Utility class to create an switchable Observable stream.

 *
 * For example:
 * ```typescript
 * const switchableStream = new SwitchableStream()
 *      .addStream('s1', obs1)
 *      .addStream('s2', obs2);
 * switchableStream
 *  .stream
 *  .subscribe(data => {
 *      // ...
 *  })
 *
 * switchableStream.useStream('s2');
 * // ...
 * switchableStream.useStream('s1');
 * ```
