FunctionStack
A simple Function-Stack class for mootools, allowing periodical calls to an unlimited function stack
How is this class different from Class.Chain?
This class differentiate from Class.Chain in few ways:
	- It is ment to be used as a periodical function caller (the playmethod)
- It allows you to pass arguments to the called functions.
- It is meant to be used as a standalone rather than be extended. This is why i chose to use generic method calls (such as play,reset,pushetc.), which will probably be overriden
Simple Usage Example
Periodical Example
Passing Arguments
Note that this can be done with play as well
