  Added:       jk/java/org/apache/jk/core Channel.java Endpoint.java
                        Handler.java Msg.java Webapp.java Worker.java
                        WorkerEnv.java package.html
  Log:
  The 'interafaces', coresponding to jk2/include ( on the C side ).
  
  I tried to keep everything as simple as possible, most are abstract
  classes. In common we'll have the different implementations.
