Wilsons algorithm implemented. Indexing different in a couple of places due to Ruby vs Java.

Implemented Aldous-Broder random walk algorithm

Implemented maximum path. This generates only one maximum path, there can be more than one of the same length.

Implemented finding shortest path from root cell to any cell in the maze.

Implemented distance calculations and ability to show or hide distance values. Due to ASCII output, max distance is 36, which equals letter z.

Added sidewinder algo

binary tree algo working.

Print row x col ASCII grid

Implemented BinaryTree algo. Needs testing or at min ability to print grid.

Math for setting neighbors was incorrect. Added tests to verify neighbors are valid.

implemented grid, a container of cells, and test cases for grid.
