isinstance(constraint, SignomialEquality) 'not working'

[1ozturkbe]

This seems somewhat trivial, but for a model with Signomial Equalities, the following does not work:

all_constraints = model.flat(constraintsets=False)
for cs in all_constraints:
    if isinstance(cs, SignomialEquality):
        print cs

However, this works:

all_constraints = model.flat(constraintsets=False)
for cs in all_constraints:
    if isinstance(cs, SingleSignomialEquality):
        print cs

This is obviously because all SignomialEqualities are of type SingleSignomial Equality. This is when I struck this gem:

        # TODO: really it should be easier to vectorize a constraint

Why is it difficult to vectorize SigEqs @bqpd? The results can be messy on the user's end.

I think there's an issue on this already; long story short, you're welcome to try, but without operator overloading it's difficult to get arrays and scalars to act the same without creating a second "interface" (SignomialEquality) to the underlying low-level constraint (SingleSignomialEquality)
