 * Rule is the class that contains the individual rules that 
 * combined govern a transition's behavior.  As it is, it seems
 * silly to have such a class when it is just a single character 
 * string, but we did it this way so we could easily accomodate 
 * PDA and possibly Turing Machine rules if we wanted to. 
 * 
 * Rule contains:
 * - String inputChar: the character this rule represents.
