Bug fix: in debugSymbols.inc, the p_nReserves and p_nuReserves are causing errors with debug mode 2, because they are actually deleted from the model. Fixing by replace both with p_groupReserves and p_gnuReserves

Removing q_resDemandLargestInfeedTransferUp and q_resDemandLargestInfeedTransferDown, as q_resDemandLargestInfeedTransfer can handle both.

Adding a new constraint q_maxDownward2 and modifying q_rampDownLimit. A small change to v_reserve.up to make it work with consumption units as well.

q_maxDownward2: similar to q_maxUpward2 but for v_gen and downward online+offline reserve provision

q_rampDownLimit: do not consider offline reserve provision

Making it possible to choose in the modelsInit.gms file whether to include the two additional incremental heat rate equations that use binary variables:
- mSettings(m, 'incHRAdditionalConstraints') = 0: use the constraints but only for units with non-convex fuel use
- mSettings(m, 'incHRAdditionalConstraints') = 1: use the constraints for all units represented using incremental heat rates
Enabling incremental heat rates also in the invest model (and potentially in the building model). Some clean-up to the incremental heat rate equations.

Implementing cyclic online states for units (inside/between samples). A new set uss(unit, s, s) added for this purpose. See issue #51.

Issue #32: Slightly cleaning up the trajectory equations by separating 'p_uCounter_runUp' and 'p_uCounter_shutdown' into minimum and maximum arrays to avoid doing partial time step calculations in '2b_constraints.gms'

Issue #32: Run-up and shutdown trajectories overhauled to permit SOS2 ramping on the last/first run-up/shutdown intervals, as well as include main fuel consumption during run-up/shutdown. However, this formulation still fails to consider changing interval lengths.

Implementing maxFuelCons and maxFuelFraction. For main fuels, the parameters function as their names suggest; for start-up fuels, maxFuelCons is not implemented and maxFuelFraction is treated as exact fraction.

Adding ramping costs. Upward and downward ramps separated into different tiers (or 'slacks') with different costs.
