    "

        I'm instance of function and I'm holded in interprete's

        funcTable. I know my name as well as namespace uri in which

        I'm. 

        To execute myself on conrete data, you have to 'instantiate' myself

        using the #instantiate to obtain so called 'function instance'. Then

        you have to fill the instance with particular content (as parameters,

        interpreter and so on) and evaluate me (I'm actually a command pattern).

        I've two main subclasses - NativeFunction and UserDefinedFunction. Note,

        that NativeFunctions is his own 'function instance'.
