CVS: plexus-container-new/src/java/org/apache/plexus/util ContextMapAdapter.java,NONE,1.1

Update of /cvsroot/plexus/plexus-container-new/src/java/org/apache/plexus/util
In directory eng.werken.com:/tmp/cvs-serv7788/src/java/org/apache/plexus/util

Added Files:
	ContextMapAdapter.java 
Log Message:
o Clarifying name of the container host.
o Using the context as the source of values for the configuration resource
  interpolation. As a result I cleaned up anything to do with configuration
  variables as this is redundant given the existence of the context.
o Created a simple adapter so that a context can be used as a Map in the
  InterpolationFilterReader.
o Added test cases for the ContextMapAdapter and the InterpolationFilterReader
  using the adapter.
