read_fas.e

-- this READ_FAS class is intended to read two files, one step at a time:
-- index file(1.richmond) is loaded first, then its contents decoded into memory using a encryption<->decryption routine designed specifically for the index file itself.
-- following that is the data file(2.toronto), which has most of its contents encrypted and packed (without using a compression algorithm at that) into, again, a data file. it, too, uses its own encryption<->decryption routine.
