Comment (by ncohen):
Okay, three questions :
- Should !BlockDesign be deprecated ?
- is `self._degrees_cache` used anywhere ? If not, remove it
- `self._incidence_matrix` is set to None even when the Incidence
Structure has been defined from the incidence matrix
- `is_simple()` does not work when the input is not copied and not
necessarily sorted.
