ManRNG - main.cpp nearing completion

/* ManRNG - a cross-platform command-line RNG generator for Pokémon games
 (c) M.andrew 2012

 This utility provides the user with access to the full range of RNG
 operations available in the popular Pokémon series of games, allowing
 him to find shiny and/or flawless Pokémon no matter what type of computer
 he is using. By default, positive results are send to stdout in CSV format,
 allowing them to be easily piped into bash text manipulation utilities
 or simply saved directly into text files.

 The ultimate goal of this program is to match the seed-generation capabilities
 of the widely-known RNG Reporter utility for Windows while supporting all
 of its major file formats, including the XML profiles of the alpha-stage
 RNGR 9.96. Once this goal is realized and a standarized format for args
 is set in place, I foresee writing frontends for the program to improve
 its ease of use for the public.
