*
* USAGE:
* - Create the Seamlessloop object
* var loop = new SeamlessLoop();
*
* - Add as many sounds as you will use, providing duration in miliseconds
* (sounds must be pre-loaded if you want to update the loop without gaps)
* loop.addUri(uri, length, "sound1");
* loop.addUri(uri, length, "sound2");
* ...
*
* - Establish your callback function that will be called when all sounds are pre-loaded
* loop.callback(soundsLoaded);
*
* - Start reproducing the seamless loop:
* function soundsLoaded() {
* var n = 1;
* loop.start("sound" + n);
* };
*
* - Update the looping sound, you can do this
* synchronously (waiting the loop to finish)
* or asynchronously (change sound immediately):
* n++;
* loop.update("sound" + n, false);
*
* - Modify the seamless loop volume:
* loop.volume(0.5);
* loop.volume(loop.volume() + 0.1);
*
* - Stop the seamless loop:
* loop.stop();
