execute in interface Function
evaluator - An instance of Evaluator.
arguments - A string argument that will be converted into two string arguments. The first argument is the first string to compare and the second argument is the second argument to compare. The string argument(s) HAS to be enclosed in quotes. White space that is not enclosed within quotes will be trimmed. Quote characters in the first and last positions of any string argument (after being trimmed) will be removed also. The quote characters used must be the same as the quote characters used by the current instance of Evaluator. If there are multiple arguments, they must be separated by a comma (",").
Returns an integer value of zero if the strings are equal, an integer value less than zero if the first string precedes the second string or an integer value greater than zero if the first string follows the second string.
FunctionException - Thrown if the argument(s) are not valid for this function.
