Use of generic constructor

I am trying to use this code to achieve different tasks:
1) simulating dwave quantum annealing process. Some questions on the parameters:
- for Gamma and Jchain can I use the values that they provide for A(s) and B(s) ?
- what about invTempJ0 and invTempH0? As far as I understand they compensate for the SQUIDs error, but maybe I don't need this level of detail, how can I get rid of them?
- can I obtain the energies? it would be nice to track the eigenvalue spectrum over an s range to see how the gap changes

2) solve Ising models: s = 1, no transverse field, it should be enough to set Gamma = 0. Am I missing anything? Is it sensible to use this library as such?
