This program generates the H-curve described in the paper
"Towards Optimal Locality in Mesh-Indexings"
[NRS97] by
R. Niedermeier ,
K. Reinhardt and
P. Sanders .
The program provides 3 algorithms:
One very simple algorithm, which only works for squares, which are a power
of the 2, one algorithm, which works for even squares,
and one algorithm, which works for any rectange, where the y-size
is taken from the same input field as the squaresize and the x-size
is taken from the second input field.
If both values are not even, the curve can not be cyclic and will end
in distance 2 (or sometimes more) right from the start.
