timer.execute - Function

execute a function periodically

Synopsis
execute(callback, interval, oneshot)

Description
execute takes a function which you supply (a ``callback''), and executes it one or more times after a time that you specify has passed. The function returns a string, which you can use in the remove function to deactivate execution of the function.

The callback function you supply must take two arguments, which will be passed to the function when it is called by timer.

interval: The time interval that was supplied to execute().
name: The name of the timing event, i.e., the value returned by execute().

Often the callback will just ignore these arguments

You can specify that the function is to be executed only once (``oneshot''), or ``forever'' (until deactivated with remove).
