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 !!
