Implemented NSTimer to recognize when the user is done writing.

Waits for a determined time after touching ends to submit digit.
Touches within the waiting time will cancel/restart the timer.
Removed the license from source files, since...

The license stated it must be included if project
redistributed in its entirety and unmodified. But
I'm modifiying, so I removed it.
The only change I made so far was buggy.

I changed the timer cancel to touch start (from touch end).
Because obvi if the 2+ touch is long, it broke.
Clear the screen when the business is done.
Edited Apple's readme to make relevant for this project.
Project file changed when I renamed the readme.
Added webget class to get response from network's web site.

The classes are used to make a request via http and return the
result from the page. Calls back to the main application.
Added progress spinner and answer popup.

Now it's pretty and understandable.
