"""
Write a program that randomly generates a 2d-list of characters limited to a, b, and c 
(use range 97 - 99) 
Print the list in table form. 
Write a function process that counts the number of a's, b's and c's, 
stores counters in one-dimensional list and returns the list. 
Write main that prints the list of counters and finds a most frequent letter in the list.
