Title	JavaScript Eliza
Author	Gonzales Cenelia
Author Email	cenelia [at] msn.com
Description	Basicaly,these program is an "Eliza" like chatterbot,it includes most of the features that could normaly be found in chatterbots that are clone of "Eliza" the first Chatbot program that was written by Joseph Weizenbaum professor of MIT back in 1966. However, the script that is, the database of input and responses is different, also i have implemented a special feature for controling repetitions that the program might make. Also, the lookup() function that search for keywords inside the database of the program uses the function "isGoodKey" that acts like an heuristic function for selectioning the best keyword that can be found in the database that match the current input.
