/**
 * Module to validate class against rules, it could be one of the rules 
 * defined in the org.unitils.objectvalidation.rules package
 * but could be also user implemented rules for other purpose.
 * 
 * Helpful in the case we want to have a project wide rule validator for classes. Simple to use with annotations.
