/**
 * This plugin demonstrates overriding the initialized() method to rename the
 * generated example classes. Instead of xxxExample, the classes will be named
 * xxxCriteria
 * 
 * This plugin accepts two properties:
 * 
 * searchString (required) the regular expression of the name
 * search.
 * replaceString (required) the replacement String.
 * 
 * 
 * For example, to change the name of the generated Example classes from
 * xxxExample to xxxCriteria, specify the following:
 * 
 * 
 * searchString
 * Example$
 * replaceString
 * Criteria
