RE: String Manipulation - Distinguishing alphas and nu

You need to write a template with a name attribute, and call it to process
the string. Pass the string to it as a parameter. This template would handle
the first part of the string, then if there's any string remaining, it
should call itself, passing itself the remainder of the string.
