Creates a word search grid with one instance of the string you choose, and fills in the rest of the grid with characters from that string or random characters. Uses a special datastructure and algorithm to keep track of additional possible instances and prevents character insertions that would make the chosen word.

WordSearchGenerator w = new WordSearchGenerator(3, 3, "run", FillType.CharactersOfTheWord);
w.build();

####2 step process

1. Inserts one instance of the input string in a random orientation and location

0r0
