Set `gn_forecasts(*, node, timeseries)` tells for which grid/flow/restype, node and timeseries combinations use forecasts and by default includes everything.

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

#65: *v_startup* divided into *v_startup_LP* and *v_startup_MIP* variants to avoid undesired behavior when using integer online variables.

Replacing *IntervalStepCounter* with *tt_aggregate* due to the poor performance of *intervalStepCounter*.

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

Some time steps in the initial sample where also linked to the central sample.

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

Also a minor speedup for setting model dimension (set `msft` etc.)

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

Uses new set `fts(f, t, s)` which is the same as `sft` but different order of domains.

Also removed unnecessary set `s_stochastic`.

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.

Long-term scenarios should use realized (`f00`) data but time structure in the scenario period uses central forecast (`f02`).

Also enables the use of scenario tree construction with SCENRED2

All variables and equations should now be cleared between solves since "--debug=2" prints the file separately for each solve. Otherwise each new file will contain the information of all the old solves as well.

Fixing an error in 'mft_lastSteps' that could result in the last two timesteps being included instead of only the last one.

Parameter `p_msft_probability` was not updated after scenario reduction.

Default is zero, can be changed via command line parameter --debug=[0|1|2].

Only calculate sample displacement (`ds`) for samples which have a defined starting point and which are adjacent to each other

Should fix #64

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

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".
