[FlopCpp] variable bounds not passed?

[Michael Chen]

I am not sure about this. But I have quite a few free variables in my model,
and the output mps, or lp files treat them as non-negative variable, which
leads to infeasibility.

I then manually added lower bounds to these variables, x.lowLimit(K) =
numeric_limits<double>::min(). however the same situation happened.

However x.lowLimit(K) = -10000 will be honored.

Maybe there is an easier way to specify free variable in  FlopC++? or remove
the default non-negative assumption?
