/*
 *Program to simulate the phenomenon known as grapheme to color synesthesia.
 * This program is written as an interpreter that recognizes and responds to:
 * -exit | terminate the program
 * -remap | redefine the mapping from letters to colors
 * -word or phrase | simply show the word or phrase in synesthetic color
