    public class GenericClassCounterRule
extends AbstractJavaRule

    A generic rule that can be configured to "count" classes of certain type based on either their name (full name, prefix, suffixes anything can be matched with a regex), and/or their type.

    Example of configurations:

         <!-- Property order is MANDATORY !!! -->
     <!-- Several regexes may be provided to ensure a match... -->
     <property name="nameMatch" description="a regex on which to match"
         value="^Abstract.*Bean*$,^*EJB*$"/>
     <!-- An operand to refine match strategy TODO: Not implemented yet !!! -->
     <property name"operand" description=""
         value="and"/> <!-- possible values are and/or -->
     <!-- Must be a full name to ensure type control !!! -->
     <property name="typeMatch" description="a regex to match on implements/extends classname"
         value="javax.servlet.Filter"/>
     <!-- Define after how many occurences one should log a violation -->
     <property name="threshold" description="Defines how many occurences are legal"
         value="2"/>
     <!-- TODO: Add a parameter to allow "ignore" pattern based on name -->
