  Added:       src/java/org/apache/cocoon/components/modules/input
                        AbstractWrappingModule.java
                        ForrestWrappingModule.java
  Log:
  AbstractWrappingModule wraps another module and can thus filter
  anything for it. The ForrestWrappingModule is ATM a boilerplate to be
  filled with the resource filtering needed to resolve the conf files.
