%% SLICE: maximum number of pieces created by a given number of slices.
%
%  Discussion:
%
%    If we imagine slicing a pizza, each slice produce more pieces.  
%    The position of the slice affects the number of pieces created, but there
%    is a maximum.  
%
%    This function determines the maximum number of pieces created by a given
%    number of slices, applied to a space of a given dimension.
