continuous scoring

[Dave Ahn <ahn@vec.wfubmc.edu>]

I just committed some changes to add continuous scoring because Swasey wanted
to look at the code.  I'll clean up the code and add a sysdef option to
disable it soon.  The scoring system is a preliminary version and should
not be interpreted as such.
