Changed the constraints for emission cap, minimum energy share, and maximum energy share so that they can be defined for a group of samples as well.

Changed parameter 'p_unit(unit, *)' to 'p_unit(unit, param_unit)' in order to avoid misspellings in the input data. Changed also sets 'op' and 'eff' to be subsets of 'param_unit'.

Added weighting for the samples to correct the calculation of annual payments. An annual payment is paid in each sample where the investment option is available and it is multiplied by the sample weight which is different from the sample probability that is used for calculating energy-based values (operating costs and energy produced).

Changed unit investment variables to not depend on the time step. The time step when a unit becomes available ("when a unit investment decision can be made") is defined in the set ut(unit, t, start_end).

Replaced q_fixedGenCap2U with q_constrainedCapMultiUnit, which enables different decommissioning and replacement decisions in addition to fixed investment ratios. Removed unnecessary parameters and divided p_groupPolicy into p_groupPolicy and p_groupPolicy3D. Renamed also the linking sets related to groups, e.g. gnu_group --> gnuGroup.

Added fixed operation and maintenance costs for investment options
Adding a new parameter unitOutputCapacityTotal to avoid division by zero
Added unit investment result parameter
Removed equation q_fixedGenCap1U
Added default value calculation for reserves update frequency
Moved tCounter update outside ms loop in 3c_periodicLoop.gms
Updated the limits of v_invest_LP and v_invest_MIP (no more maxGenCap, minGenCap)
Updated investInit_temp.gms
And some smaller updates

Continuing to fix the reserves in the deterministic mode. Now they should also work after the first solve.

Release of tertiary reserves for the realization released also primary and secondary reserves. Now corrected, but the selection of reserves should be moved to the input file along with the new set members for reserveTypeReleasedForRealization.

Deterministic model (mSettings('...', 'forecasts') = 0) is corrected to have a model horizon up-to t_horizon (used to be only up-to t_jump).

Boundcyclic again only for the first timestep, as it otherwise confuses the building thermal modelling. Tertiary reserves are now able to replace primary reserves during realization, if necessary.

Tertiary reserve demand now vanishes entirely during the realization, allowing for constant tertiary reserves if desired. Startup for the first timestep is no longer required, which assumes that the unit has been online before the model horizon.

Implementing temporary forecast and time displacement arrays to slightly improve "inputsLoop" performance.

Reorganizing the result calculation to improve performance by moving all possible calculations to the end of the solveloop.
