Kidney CA. Have now updated the passing of variables used to pass variables through to graph them from the base functions. This allows simple change of f_implementation_move and a few others to pass back variables of interest to the front. Have also updated the gui to allow the user to specify the number of non-local jumps allowed along the principal and secondary axes. Have also added a new graph allowing the user to see the number of spots available for mesechyme as well as the breakdown (for epithelium moves) between vacant spaces vs mesenchyme.
