Re: Expression parsing.

As a follow up on the ARDAF classes... here's the official blurb from the
sparse documentation:


    The ARDAF engine allows variables, arrays, functions, complex domain
        math, and standard algebraic notation. Consider the following code
        fragment:


                CArdaf expr;
                expr = "a := 10";
                expr = "square_root(x) := 2}x";
                expr = "square_root(a-11)";


                cout << expr.Solve() << endl;


        The result of the above, if the ARDAF engine is compiled to allow
        complex domain expressions, will be:


                0+1i


        Unlike standard programming language expressions, ARDAF expressions
        can be in standard algebraic form:


                CArdaf expr;
                expr = "f(x) := 2x";
                expr = "3f(4)";


                cout << expr.Solve() << endl;


        The above results in an output value of 24. Note that "x2" is a
        complete variable name, whereas 2x means "2 times x".
