Parses a ParseTree as a arithmetic expression @param T arithmetic type. By default is float. @param grammarName Name of the arithmetic grammar. Must be "ArithmeticNoVar" or "Arithmetic". By default is "ArithmeticNoVar" @param ParseTree p ParseTree generated by ArithmeticNoVar @param variable Associative array with variable values @return The result of the arithmetic expresion. If the ParseTree is invalid or contains unexpected nodes, then will return NaN if T is a float or 0 if T is a integral

This module contains a example of a reusable arithmetic expression grammar and a recursive ParseTree parser that returns the evaluation of the arithmetic expression
