/*

  CoreTestSubComponent will test the various ways to use SubComponents.
  The SubComponents will be loadable as both named and unnamed
  SubComponets.  When an unname SubComponent is used, it inherits the
  port interface from the BaseComponent that created it.  A named
  SubComponent owns it's own ports and will mask the ports from any
  BaseComponent higher in the call tree.

  Each BaseComponent will have a port(s) that may or may not be used
  depending on the configuration.
