Detailed Description

Mapping between integer intervals and integer rectangles.

This class implements a bijective map between the subset [n0,n0+size-1] of Z and the subset [llx,urx]x[lly,ury] of Z^2 via the x-major-scheme (y varies fastest) :

 (llx,ury)                                 (urx,ury)
          +  n0+ny                        +  n0+(nx*ny) -1
          .
          .

          +  n0+1

          +  n0     + n0+ny+1   ...       +
 (llx,lly)                                  (urx,lly)
