Comment (by ncohen):
> Could we move ` _relabel_bibd` as a method of
`BalancedIncompleteBlockDesign`?
Hmmmm.. Well, it woud mean that we have to build BIBD objects during the
recursive constructions too... I'd prefer to keep it this way if you don't
mind `:-/`
> (not very important) Why did you put the classes
`PairwiseBalancedDesign` and `BalancedIncompleteBlockDesign` in the file
`bibd.py` and not in `incidence_structure.py`? I am not sure about what is
the best organization should be, but right now it is not clear at all
where to look to find something.
Well, that `BalancedIncompleteBlockDesign` is defined is `bibd.py` is
hardly a surprise. I feel that PBD are very close to BIBD but indeed, if
GDD are in !IncidenceStructure then indeed it can be moved there. What do
you think ?
