Auto translate PB constraints to clauses

[MaxOstrowski]

Automagically translate some of the pb constraints into clauses, with a similar heuristic as clasp does.
Isn't this the same as simply translating the original linear constraint into clauses instead of using a PB constraint ?

This depends on the translation we implement. For example, clingcon's constraint to clause translation does not introduce auxiliary variables. Some PB-translations introduce auxiliary variables to achieve more compact representations. Introducing auxiliary variables is actually also something interesting that could be considered when translating constraints to clauses.
