/* read/write methods for binary files

binary fstreams use one feed for writing and one feed for reading: g(et) and p(ut)
the tellg() and seekg(int) methods respectively print and set the positions of the g-feed
analagous methods exist for the p-feed

call fstream::write(char* memblock, int size) ; memblock points to data to write at tellp()
call fstream::read(char *memblock, int size) ; memblock points to location to write to at position tellg()

in both of the above methods size is either nBits or nChars - but which???
