---------------------------+----------------------------
This is a follow-up on #18734.
This ticket creates:
- a new class, `LPBackendDictionary` (inheriting from
`LPAbstractDictionary`, would avoid InteractiveLP and rather be tied
directly to the MILP backend, using tableau data query functions such as
`getBInvArow` etc.
(It would be in a separate file perhaps
`interactive_backend_dictionary.py`, so as not to add clutter to the
didactical implementation in `interactive_simplex_method.py`.)
#18732 adds the missing functions for retrieving the data of the
dictionary (for the GLPK backend) such as `getBInvARow` etc. (#18763 does
the same for the COIN backend.)
#18733 provides corresponding `MixedIntegerLinearProgram` methods.
Doctests could then test that:
- A backend has implemented all the necessary methods to get tableau
information.
- The information is consistent, by checking that the
`LPBackendDictionary` (in this ticket) and the `LPDictionary` (created in
#18734) are the same.
