// Program implements the game of Boggle by generating a Boggle board
// then asks the user to find as many words as possible on the baord.
// The program locates all words on the board and checks the dictionary
// to see if they are acceptable Boggle words. Each word is then
// scored and a final score is displayed to the user. The game
// also displays all valid words on the board which the user did not
// find.
