mei_rt2mei_rt2_fix_1

Last change on this file since ed3dc05 was 5110d42, checked in by Mei <mei@…>, 13 years ago

1) reorganized the test directory to include python tests
2) attribute via api and principal via api from python scripts is

working (although there is a annoying seg fault at the very end
that must be related to something not been dup()ed.. need to wait
for c example to debug it)

3) able to query via api
4) replicated access_rt2 example in python and the query result matches
5) expanded api to make it easier to generate rt2 structure

Property mode set to 100755
