Commented out some debug timing code for measuring performance cost in overlap().  The calls weren't cross-platform, so this was preventing Windows version from building.  Also was not even printing out timing results any more, so looks like it wasn't used.  Might have also been causing a performance hit since it may have been in a computationally intensive part of the code.
Fix for SVS windows build.  One of the models was directly including the linux portability file.
Removed readme file that had no current information.  Removed old patch file.
