The generator function takes an optional options object, with these options:

diagonals (boolean)

Defaults to true. Determines whether words can be placed diagonally on the puzzle.

width and height (integer)

Defaults to 10x10. Sets the size of the puzzle.

minLength and maxLength (integer)

Useful for making sure the words aren't too short or too long. The default for minLength is 3, and for maxLength is undefined.

words (array of strings)

Words will be chosen randomly from this list. If this is not provided, it uses a built-in set of around 2,000 words.
