Rewrite of the boundCyclic equation to reduce the time it takes for Backbone to generate it. This might need rethinking in the future if more complex sample bounds need to be considered.

df changed to record all displacements in order to make it work properly with references to historical startup/shutdown information.

Rewrote 4a_outputVariant to match the new forecast-time structure. Model should be able to run now, but the structure still has to be excessively debugged in order to make the outputs make sense.

Also moved ft_nReserves definition inside the interval loop in order to possibly save an insignificant amount of execution time.

Rewrite of the equations for the ft changes, as well as a host of smaller changes and improvements to code readability

Online variables between MIP and LP variants made to use same units. New sets for LP and MIP online variables. Removed q_boundCyclicSamples and q_minDown as redundant and made the appropriate changes to q_boundCyclic and q_onlineLimit. Removed q_boundState entirely due to it being redundant with q_boundStateMaxDiff.

Adding a constraint for minimum kinetic energy and updating the constraint for maximum instantaneous share

Setting ramping limits in 3d_setVariableLimits.gms for units without online variable and without investment possibility.

Added the ".holdfixed" option to the solve commands, which should make the GAMS compiler convert fixed variables into parameters before feeding the problem to the solver.

NOTE! Regarding the last change concerning the inclusion of flow units into the suft sets: Now conversion equations are generated for flow units, which is required for EV batteries. However, without a defined "fuel" or input energy, traditional flow units (wind, solar, RoR) stop generating energy due to the seemingly nonexistant energy source. This problem can be circumvented by defining free "fuels" for flow units, but is a rather unnecessarily convoluted way of handling things.

Note: q_genRampChanged redefined

Git ignore update (added a folder sandbox, which is not in the Backbone project for testing purposes)

Flow units are now included in "suft" and "sufts", not entirely sure why this was not the case before.

This is required for the current EV implementation, as the battery charging and discharging are controlled by "EV" and "PHEV" flows.

Several conflicts resolved

Added constraints for the maximum and minimum share of generation from a particular group of units over the solve period

Added a constraint for maximum instantaneous share of generation/import from a group of units/transfer links

Fixing minimum up and down time constraints to take into account realized startup and shutdown decisions from previous solves

Temporary fix, that allows for units to start immediately (as opposed to the previous locked "v_online" on the first step of "ft_realized"). Caution is advised!
