I want to extend it to add functions that i need

[umairzafar]

This is a great library and you guys have done a great work. I am using it for evaluating functions within expression and I am looking for a way to add functions those are not available. To do that i tried to extent it but Extend method under ExtendedExpression class is marked as internal so i can't do it. Just so you know I want Base64 and MD5 conversion functions. Thanks
