Avoid Compounding Non-Idealities

[coreylammie]

To avoid compounding non-idealities, two seperate conductance matrices can be stored for each layer/module: (1) with all non-idealities applied, and (2) with no non-idealities applied. A list can be added to each layer/module containing all of the applied non-idealities, so that these can be reapplied to the conductance matrix with no non-idealities are applied when new conductance values/weights are programmed.
