PFC - Provide File Comments

Accordig to Sun Code Conventions for Java, all source files should begin with a c-style comment that lists the class name, version information, date, and copyright notice: `
/*

This audit rule verifies whether the file begins with a c-style comment. It may optionally verify whether this comment contains the name of the top-level class given file contains.
