%% Should it be able to return a cell size aswell? For an equidistant grid this would be know
%% for other grids the constructor would have to make something up.
%% For example the grid.Cartesian constructor would take a h (1 x d) vector as an in parameter.


%Should define boundaries somehow, look in stitchSchemes.
