added xcode project

cleaner error reporting
added generic numpy support (not working)
use lock count instead of message queuing to avoid py->py messaging deadlock
fixing strange gcc behavior
fixes for maxmsp
support for buffer objects (preliminary)
fixed reference count bug
use optimized version
updates for DSP processing
adjust pd and py files for correct argument passing
more optimizations
fixed numarray headers
little restructuring
