[MOAB-dev] MOAB examples

[Jason Kraftcheck]

Why do we have subdirectories under examples/ when all of our examples (by
design) are a single file?  Is it just so that each can have its own
Makefile?  Would anyone mind if I were to move all the example source files
to the top examples/ directory and remove the individual subdirs?  Would it
be a problem if all of them were to share a single Makefile?  This would
result in a simpler build system with fewer files to maintain.
