Function Parameter Tokenizer. 
<p>
This is an helper class that separate each function argument and allow to acces them individually.<p>
Once the parameters have been parsed, the client init method is called and the object is pushed into the compiler stack. This way, functions can have their own state.<p>
The implementation is on the header file to allow plug-ins to only include this file without having to link with the library.
