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.

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.

Preparing to fix issue #55: including temporary time series definitions. Rest of the fix will be implemented in the branch "46-add-sample-dimension" to avoid duplicating the work after the upcoming merge.

Fixing issue #32. The last time interval in the run-up phase had a wrong limit for the q_rampUpLimit, this was corrected by calculating a new parameter p_u_maxRampSpeedInLastRunUpInterval. This might not be the only thing wrong. Needs to be checked futher.

Updating issue #47. It should now be possible to use same reserve for multiple categories. So, a unit can have a multiplier in the new table p_nuRes2Res indicating the ratio at which e.g. primary reserve from the unit can contribute to secondary reserve.

Note: Smoothing for ts_node is not implemented yet

Removing 'dt_noReset' as unnecessary, now that 't_active' and 'dt' cover the required model history.
Also fixing the calculation of 'dt' for the first time step in 't_active'.

Activate this feature using active('scenRed') and setting mSettings parameters 'red_num_leaves' or 'red_percentage'.

Samples can now be used to describe uncertain future after the forecast horizon

Added a new optional model setting 'dataLength', which allows for explicitly determining the desired length of data used before 'dt_circular' starts recycling it.
Changed the calculation of maximum data length to find the largest 'ord(t)' with defined data instead of the old counting of found values.
Removed an unused scalar 'stepsPerInterval'.

Removing the "t_activeNoReset" by including "tmp_dt" historical time steps into "t_active" and avoiding loops over the entire model history.
Implementing a new "unitCounter" set to limit excessive looping over the "counter" set in unit startup/shutdown constraints.

Removing the ill-defined "p_nnReserves(... 'ratio')" parameter and replacing it with relative capacity bounds similar to "p_nuReserves(..., up_down)".
"restypeDirectionNode" set also changed to be more inclusive to avoid issues with not generating "q_resBalance" equation for nodes with no reserve requirements, but still connected to nodes with reserve requirements or units with reserve provision capabilities.

Renaming "df_nReserves" to "df_reserves", changing "mft_nReserves" to "ft_reservesFixed", as well as a lot of accompanying changes.

Changed 'ts_nodeState' to 'ts_node' for clarification (since penalty time series should also be implemented, which does not refer to the node state)

Updated some terminology and changed the effLevel determination from start time step to end time step. Addresses issue #19.

Enable the use of advanced basis. Three options: use the latest solve, use all solves from the previous run, use the first solve from the previous run.

Include t00000 for storage and online variables for the results output (as long as there are variable values for the first time period).

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

Also changing the length of the forecast horizon so that it is now possible to either keep a static length for the forecasts or to have a decreasing forecast horizon that only extends forward at every tForecastJump.

Several fixes to get intervalLength > 1 working. Still needs some fix if intervalLength > 1 for the first steps in the horizon (dt for the first time step not calculated properly).

Updates to run-up phase. Added unit conversions from p.u./min to p.u./h and multiplication by intervalInHours for p_u_maxOutputInLastRunUpInterval and p_ut_runUp. Tested only with deterministic run, intervalInHours=1 and intervalLength=1. Calculation of dt_toStartup probably needs a fix for other intervaLengths than 1.

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'.

Fixes and clean ups. Most importantly a term in the q_maxUpward was updated to point to the correct start up time period (hopefully).

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.
