** PlayHead

PlayHead is a simple stop watch object that can be used where we need to keep track of time as well as we need to pause, forward, rewind and stop. It returns the current running time using a public method. playHead.runningTime();

Good new is that this object has no dependincies.

Following is the API

• To start the counting playHead.play();
• To pause the counting playHead.pause();
• To re start the counting playHead.stop();
• To forward the counter playHead.forward(milliSeconds);
• To rewind the counter playHead.rewind(milliSeconds);

and finally at any time we can check for the lapsed time

• To check the current running time playHead.runningTime(milliSeconds);

-- Further Notes:

• It has 2 optional variables that we can give to it while creating the object
  • Duration: the length of the time to be counted (in minutes). However at the end of this time the counter will not stop. This may be implemented in future.
  • paused: It decides if the object should start paused or not.

• Both of the above variables have not yet been implemented.
