Changed structs.py to export the original names of the C structs, not uppercase.
Totally rewrote pyassimp, removing all pyassimp classes, instead using python's dynamic nature to expand the ctypes structures to include safe array access and python style tuple access. Updated helper.py and sample.py. git-svn-id: https://assimp.svn.sourceforge.net/svnroot/assimp/trunk@406 67173fc5-114c-0410-ac8e-9d2fd5bffc1fpull/1/head
