multi_array and friends should provide the number of dimensions as a static 
member constant, so it is available at compile time and can be used in 
generic programming.  I assume the num_dimensions() non-static member 
function was put in the design with the idea that the number of dimensions of 
a multi_array object might be dynamically changed.  But since the multi array 
concept and classes doen't support changing the number of dimensions, it 
doesn't provide anything useful over a static constant.
