From 6cdf084fa40a62eb33185171622ad12d95c6009e Mon Sep 17 00:00:00 2001 From: Dan Sinclair Date: Tue, 8 Mar 2016 13:49:22 -0500 Subject: Remove xfa/src/fxfa/src/common and xfa/src/fxfa/src This Cl moves the code in xfa/src/fxfa/src/common to the diretory which contains the respective implementations and removes the xfa/src/fxfa/src/common directory. It them moves all of the code in xfa/src/fxfa/src up one level and removes the xfa/src/fxfa/src directory.
