Clean up combinatorial helpers.

* Convert all signatures from int to unsiged.
* Renamed partition_generator to partition_with_zero_parts_generator...
* ...and add class partition_generator which does not include zero parts.
*  Rename ::current() to ::get() and make them compute vectors on first use.
