bit of src tree shuffling. main.cpp to be replaced with test programs

full disclosure: i'm a bit unsure of what is the best way to do this
at this point in time. the end goal with this project is that it
becomes a library to be used by other apps (of course), but need tests
to test various library functionality. unsure how best to organize this
with cmake (and since i'm using clion, i kind of would prefer it works
nicely and integrated with the ide...).

i figure this is going to be a trial and error approach that will
evolve over the next while
