Updating the two ROCOF constraints so that they apply to a group of nodes instead of individual nodes.

The transfer ROCOF constraint considers failures of interconnectors with one end inside the group and one end outside the group. 'DefaultFrequency' and 'ROCOF' are now p_groupPolicy parameters instead of p_gn parameters.

Now the ReserveShareMax could control its reserve type and direction with the newly introduced p_nReserves3D which should also be reflected as a new sheet in the excel file.

Added a conditional to the equation and added the portion_of_transfer_to_reserve also to reserve transfers.

The reserve for largest interconnector(transmission line) is included, with separate equations for up and down reserve

Ciara's codes:minCons constraint allows to set the min load for PHS while still allowing foll reserve

*intervalStepCounter* now uses (counter, t) instead of (counter, counter_) due to the counter set being too limited in size.

Rewriting large portions of *3c_inputsLoop.gms* to make it more compact, and hopefully increasíng performance as well.

Changed behaviour of `mSetting` 't_perfectForesight' so that it’s defined from zero (not after 't_jump')

The setting does not have any effect if 't_perfectForesight' is less than 't_jump'.

New model setting `t_perfectForesight` gives number of time steps after `t_jump` where realization foreast is used

Parameter `df_scenario` should be used only for stochastic data (nodes). Also using maximum downward slack and minimum upward slacks in time series aggregation as this was not implemented.

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.

New data parameter hrsection defined (using section will change Lambda results)
Slope for incremental heat rates now defined based on max efficiency (not used in conversion constraints - approximation only required)

Also enables the use of scenario tree construction with SCENRED2

Adding a possibility to use constant fuel prices instead of time series ones. NOTE! Contains a 'trick' to avoid additional inputs for convenience.

Renaming 'shutCost' to 'shutdownCost' to be more consistent with the current naming scheme, and included it in 'param_unit' to avoid errors if not defined in data.

Revenge of issue #59: Assuming no active features, so the model execution is not interrupted if no active features are declared.

Issue #59: Model features can now only be activated through the model definition file. Commented out the features that have not bee implemented for clarity.

Issue #55: Added a new 'param_eff' set for 'ts_effUnit' and 'ts_effGroupUnit', used 'param_unit' for 'ts_unit' for the time being. Created 'unit_timeseries' set to simplify writing conditionals for units with time series data. "inputsLoop" should now work for 'ts_unit', but the nature of 'ts_effUnit' and 'ts_effGroupUnit' should be further discussed before their inclusion into "inputsLoop".

Solving issue #27. Allows to set v_gen for the first time step of the first solve (e.g. t000000). Use useInitialGeneration and initialGeneration in p_gnu to get this to work.

Adding an option for linear improvement of the central forecast toward the realization, controlled by 'mSettings(mType, 't_improveForecast)' instead of the old 'f_improve' parameter. Also added readiness for updating only existing values when updating forecasts (currently commented out), as well as removed some old unused code.

-Removing the unitFail set (unit_fail set is directly read from the input GDX)
-Deleting N-1 param_policy (Infeed2Cover can handle its task)

Included the 'N-1' parameter into 'param_policy' to avoid errors if no "p_nReserves(node, restype, 'N-1')" are defined.
Additionally, reorganized and highlighted the reserve related parameters in 'param_policy', as they hopefully will be moved to a dedicated parameter set at some point.

Adding 'reserve_length' to 'param_policy' to avoid missing label errors with input data without reserves.
Also a minor clarification to 'q_conversionDirectInputOutput'.
