Includes functions and subroutines, stack underflow issues now have error trap. Need to tighten parser to watch for mal formed function/endfunction.

continued work with functions. local variables in functions work, string functions, numeric functions, functions returning values. need to work on passing values to functions - not there.

Finished and refined compile time errors for IF THEN, DO, WHILE, END IF, END WHILE, UNTIL, FOR, NEXT, and ELSE if they do hot have a matching opening or closing statement. Does not check variable in FOR/NEXT just that the right statement is nested next.
