  Added:       proposal/myrmidon/src/java/org/apache/myrmidon/components/executor
                        DefaultExecutionFrame.java
  Log:
  Default implementation of frame that just caches values passed to it.
  
  The exception being TypeManager which it uses to create a child TypeManager that is relevent to frame.
