r_genFuel was not working. Trying to fix it, but now it works only for units that have one input commodity - the results will be wrong if there are mutliple. Needs to be fixed later. I also added flow based generation. So, r_genFuel should really be r_genSource

#107

Changing the calculation of r_gnRealizedOperatingCost (and its derivatives) to use energy based allocation for fuel, emission and startup costs.

A couple of bug fixes to #107, according to suggestions in #107 (comment 14595)

Changing p_price dimension and updating ts_vomCost_ calculation. Some stylistic updates to ts_startupCost_ calculation as well. (issues #107 and #120)

Replacing the "*" dimension with "param_policy" in some reserve parameters to avoid any typos and mistakes in input data

One gnu_input/output fix in the constraints and updating start-up emission cost and total emission calculations (issue #107).

#107

# Conflicts:
#	inc/2d_constraints.gms

Taking into account reserve reliability and reserve demand feasibility dummy variables in q_inertiaMin (see issue #103).

Some clean-up to 1a_definitions.gms. Some of the unused params are now commented out but could also be deleted if we are agree that they will not be implemented in the near future.

Updating some checks related to lastStepInIntervalBlock and stepPerInterval that only make sense in the schedule model where all realized time steps need to be modelled with the same accuracy

Updating how emission costs are calculated. The previous version did not seem to work but I'm not sure if the new version works in all situations either. Should be checked.

1) Updating 1e_scenChanges.gms according to the new inputs, 2) adding a new constraint q_unitGreaterThanConstraint, and 3) fixing a few constraints to work with the invest model as well.

Improving #107 based on Jussi's comments. Removing un_commodity from input files - the set is formed based on commodity set as well as p_gnu (it has to have capacity, unit_size or conversionCoefficient). Also, removed automatic calculation of p_uStartupFuel -> it needs to be in sheet p_uStartupFuel even if there is only 1 startup fuel (use fixedFuelFraction = 1)!

Something failed with pre-compiled conditionals in the scenred. I got them to work only by moving them to the beginning of line. Tabulated the file properly while at it.

First working commit for the new inputs and outputs system. Probably buggy... In Google Drive there is 8unit system excel that works with this (vInputOutput.xlsx).

Error occurs if t_trajectoryHorizon is too short (less than t_jump + max start-up / shutdown trajectory). Avoids infeasibilities in q_startshut

For results, vOM costs were calculated only from outputs, but they can also be in inputs nowadays. Corrected.
