Although this looks like a load of code changes, this represents no functional

change to the Taf system.  Really all that's happened is I've broken out the
core taf data types into seperate files, and gone ahead and created a helpful
new header file ("taf.h") that will include the entire taf system, including
the reader and writer for you.

This means that a lot of programs will start complaining, but fortunately,
there's an easy solution, if it complains about taf, make sure to include taf.h
at the top, instead of other taf files and you'll be set.

The next set of changes will add lots of helpers to the taf system and change
the reader to read non-const structures, i.e. I'll actually add editing support
to created taf structures.
