  Added:       modeler/src/java/org/apache/commons/modeler/ant
                        ServiceTask.java
  Log:
  The service task is a grouping of mbeans. It'll be possible to perform different
  operations on the whole group. Right now it just executes the default ( init/start).
  
  This simplifies a lot the syntax of ant files that control services like tomcat.
