zexy-2.0:
- use of abstractions for objects that allow it - some objects are build both as externals and abstractions (as slower fallbacks) - code-layout is now 1:1 c-file<->object (this should allow for building of zexy as a collection of externals instead as a big library) - matrix-objects have moved to iemmatrix !! svn path=/trunk/externals/zexy/; revision=2641
