sortix--sortix/libmaxsi/process.cpp
Jonas 'Sortie' Termansen fec176fa15 Refactored the libmaxsi/ directory.
C and C++ files are now kept together and so are the mxmpp declarations.

Header files are now stored in include/ and mxmpp'd into preproc/.

All other code now -I ../libmaxsi/preproc.

And other stuff to make this happen, including refactoring Makefile.
