Implement a boolean IsNumeric(string) function in the expression language

[sitsko]

Please add an IsNumeric(string) function to the expression language.  There is a basic need to test if a string is numeric and return a boolean value.

This is a basic function that exists in pretty much every language and the absence of it in PA / Flow is baffling.
