c2m(chessMove)

function matrixMove = c2m(chessMove)
% c2m converts a chess move (e.g. d2-d4 to a matrix move)
%
% Inputs:
% * chessMove ... chess move (e.g. 'd2-d4')
%
% Outputs:
% * matrixMove ... move in matrix notation, BUT is a cell array (e.g. 'd2-d4' becomes {[7 4],[5 4]})
%
% Example
% Transform a chess move to a matrix move
%+ ca = c2m('d2-d4') % i.e. ca{1}=[7,4] and ca{2}=[5,4]
%
% Note: this function is pretty robust allows 'D7-e1', ' d  3-  D4' or 'e2e4' 
% Application: Can be used to move chess figures using the stopCursor function, 
%   for instance stopCursor( c2m('d2-d4') )
%
