should IS tax loss used be determined by IS taxes before deferment? #64

Currently IS tax loss used depends only on the stock IS Tax Loss Carry Forward.

Tax losses must be used up within 7 (?) years.

Can we keep to this restriction and have the IS tax loss used flow be dependent on IS taxes before deferment?

Fixed in https://github.com/NREL/BioproductTransitionDynamics/commit/f86ec5e4a1a2e92e3e92e309745cfb3513a52fd6. We used an exponential approximation to the MARCS depreciation schedule, which is satisfactory for this computation that plays a minor role in the model.
