initial bare commit
restructuring the flowPipe class
finished most of the implementation of flowBlock and flowPipe, significant work on flowGraph
started dynamic library handlers
minor changes to flowGraph
rehashed a lot of structure for the way pipes are put together.  Makes more sense now
added generic math operations to the generic library
i have now added a file source/sink, and next step will be to try to get this to compile and run a simple file modification program
pretty much have touched most of the files in order to get everything to compile properly
moved over to the cmake build system
block_packages is now buildable and generic ACTUALLY builds
fixing errors as I step through the code... currently looks like generic lib isn't linked correctly
adding missing files to make things work
fixing minor compile issues on mac
got rid of a bunch of warnings in dspflow build process
fixed some compilation errors on mac os x
still working on getting rid of initial debug errors
starting to restructure how add, subtract, mult, div are done to avoid duplicating so much code
forgot to add template_arithmetic
finally have a generic template which takes care of all simple functor-related processing
