Charm++ parallel programming system

[Phil Miller <mille121 AT illinois.edu>]

Here's a thought on preventing these sorts of hassles:

During each build, run 

find src -name '*.{decl,def}.h'

and the same for examples/ and tests/, and error out if anything is found. They're never going to be desirable

I figured out the problem: there was a left-over CkLoop.decl.h and
CkLoop.def.h in the src/libs/ck-libs/ckloop directory.  These got linked
over into the build directory instead of being regenerated.  Thanks for
the help.
