        //

        //  Set the formula to use, replace attributes and variables with letters 

        //

        //  e.g., this:

        //  Expression.Body="ciel(((({ProposedNetUsableSquareFeetNUSF} * 1.35) / 1000) * 5) / 25) * 25"

        //

        //

        //  "ceil((((n * 1.35) / 1000) * 5) / 25) * 25"

        //

        // 2) functionSignature variable:

        //

        //  Set the function signature.

        //  In this case, we have one variable, "n", so the signature would be:

        //  "f(n)"

        //

        // 3) functionWithValue variable:

        //  Set a test value for each variable and write out the function signature to call the function.

        //  For example, if we want to test with n=52000, we use this:

        //  "f(52000)"

        string formula = "ceil((((n * 1.35) / 1000) * 5) / 25) * 25";   

        string functionSignature = "f(n)";

        string functionWithValue = "f(52000)";

        string functionWithFormula = functionSignature + " = " + formula;
