This class can find similarities in a 2D tile matrix.

It can generate a bidimensional array of a given size and populate it with random letters from a given set of values.

The class can traverse the generated array to find similar sequences of values following a given set of directions of connected neighbor values.

The class can also display the array in a Web page highlighting the similar connected values.

2D matrices are often used to solve problems of algorithm implementation, geographic mapping and gaming.

This class can find matrix similarities using 2D arrays. It can be useful for instance to determine if players in a 2D tile game have achieved goals determined by the trails of the tiles that they traversed.
