A regular expression matching class names, see the Java Language Specification 2.0 section 3.8 (Identifiers). 
One caveat: I have decided to outlaw use of the unnamed (top-level) package for controllers. 
This ensures that the user cannot mistakenly put in something like an IDREF, thinking it possible to reference controllers.
This policy can be changed by modifying the ending '+' to a '*' in the regular expression.
