Many -- restructured header files

No longer called trm_ but instead sit inside a sub-directory called trm to avoid polluting include directories.
Series of files withdrawn

Restructuring of header files, many renamed. Giving up on attempt to document API -- not reliable enough
Lots of new files

These are renamed versions of old ones.
doc/Makefile.am -- retired Doxygen line

Never really worked.
Makefile.am -- export stuff removed

Going to rely on github from now on.
configure.ac -- new version

2.0, substantial change of file structure, now backwards compatible.
