Fix object so it is subclassable, add test for this
more code cleanup for object handlers, not yet complete
placeholders for exist and replace code
Set cleanup - add gcc4 visiblity rules

mainly in btree.c

Major changes

1. more atomic writes and reads - two calls vs. 3 or 4
2. search is now read locked only
3. error handling added
4. error functionality
5. addition of "exists" functionality using read locked exposed search api

All current tests pass, but more tests still to write,
along with some todos to finish
Work on C test suite
Added lorem ipsum to use to populate a tree
added test runs to makefile
Rest of C tests are now cooperating
