From fb5055947efd78e0e7f8a2bfd5b754c63dbb6076 Mon Sep 17 00:00:00 2001 From: dsinclair Date: Thu, 20 Oct 2016 06:44:03 -0700 Subject: Merge the CFWL_*Imp classes into the IFWL_* classes. This Cl merges the implementation classes up into the IFWL classes as the intermediate classes were just acting as proxies.
