cBogle 1.0

This is a variation on the popular letters game currently produced by Hasbro.
The aim of the game is to make as many words, of 3 letters or more, from a 4 x 4 grid or random letters.
The game is played by either type your word into the entry box or click on each letter in turn. A double click on the last letter will submit the word. Clicking on the letter twice without a double click will remove the letter from the list.
Any letters used must be adjacent to each other in any direction and each letter can only be used once in a word.
