 * Fast, primitive (taken seriously) coordinate class.
 * Coord converts two ints (X and Y) into one long (C) and
 * C back to X and Y. This class also is able to multiply
 * and divide coordinates (by ints only due to possible rounding
 * error). Due to rounding errors outside of the Coord
 * class, the get1337 method is able to "fix" these by
 * adding 1 to any value larger than 0.
