Flask displays full chess board
Remove old "test_brandon.py"

This was just an example test file.  Real tests for this functionality
are now working as part of "test_pieces.py" so this file itself can go
away.
Fix the path PyGame uses for chess icons
move()

I think this should work. The test is not working but I m not sure that
boards can be compared to each other.
Changes to Move()

I made the change to the move() function but now it gives me an Index
Out Of Range error whenever I try to look up or reassign an item in th
new board. It also dos not say the copy is == to the original.
#18?????

I think this is what you had in mind for #18 but it does not seem to
make it much shorter so I am not sure.
#17

 Pygame now displays a caption
#16 piece movement

The rook now moves diagonally until it goes off the screen.
not really anything
#20 in_checkmate() and how_to_checkmate()

I added two methods. They are both untested. One should check to see if
one color is in checkmate and the other should return all of the moves
that would cause checkmate.
