I've modified the ParsedFunction interface to support additional user defined arbitrary variables. We've been using this for awhile so that users could define more generic functions to the parser like this:
"alpha*sin(beta*x)" Then later you can define the values for alpha and beta. Actually you could potentially provide a different value for these variables each time you evaluated the function if you wanted to but that would require making a few more setters/getters to return references to the user where they could provide those values. For now, I've just added additional default arguments to the constructor in this patch which may or may not be the right way to go. Also, I've changed the local "variables" array into a class variable since we'll need to keep those additional variable values around in between normal space/time evaluation calls. These changes are all compatible with the current API. Please let me know if you have any comments. Thanks, Cody
