boggleboard 1.0.5

A package to generate and manipulate Boggle-style boards. Boards of different
sizes can be randomly generated, and given a list of acceptable words, the
package can find all words in a particular Boggle board. Currently, the package
offers standard nxn Boggle boards, arbitrary rectangular Boggle boards, and
toroidal Boggle boards (i.e. boards where one can scroll from the top row to the
bottom row and vice-versa, and from the left column to the right column and
vice-versa).

Additionally, the package contains an anagram-type solver, such as finding the
words in a Scrabble hand.

Boards of arbitrary shapes and sizes can be made by subclassing the
AbstractBoggleBoard class and specifying an adjacency graph using the positions
of the board as nodes.
