Implements gas lift optimization for groups. Extends PR #2824 to include support for GLIFTOPT (item 2, maximum lift gas supply for a group) and group production constraints. The optimization is split into two phases. First the wells are optimized separately (as in PR #2824). In this phase LIFTOPT and WLIFTOPT constraints (e.g. maxmimum lift gas injection for a well, minimum economic gradient) are considered together with well production constraints. Then, in the next phase the wells are optimized in groups. Here, the ALQ distribution from the first phase is used as a starting point. If a group has any production rate constraints, and/or a limit on its total rate of lift gas supply, lift gas is redistributed to the wells that gain the most benefit from it by considering which wells that currently has the largest weighted incremental gradient (i.e. increase in oil rate compared to increase in ALQ).

GasLiftGroupInfo &group_info,
Improve debugging tools in gaslift code. Introduces a gaslift debugging variable in ALQState in WellState. This variable will persist between timesteps in contrast to when debugging variables are defined in GasLiftSingleWell, GasLiftGroupState, or GasLiftStage2. Currently only an integer variable debug_counter is added to ALQState, which can be used as follows: First debugging is switched on globally for BlackOilWellModel, GasLiftSingleWell, GasLiftGroupState, and GasLiftStage2 by setting glift_debug to a true value in BlackOilWellModelGeneric. Then, the following debugging code can be added to e.g. one of GasLiftSingleWell, GasLiftGroupState, or GasLiftStage2 : auto count = debugUpdateGlobalCounter_(); if (count == some_integer) { displayDebugMessage_("stop here"); } Here, the integer "some_integer" is determined typically by looking at the debugging output of a previous run. This can be done since the call to debugUpdateGlobalCounter_() will print out the current value of the counter and then increment the counter by one. And it will be easy to recognize these values in the debug ouput. If you find a place in the output that looks suspect, just take a note of the counter value in the output around that point and insert the value for "some_integer", then after recompiling the code with the desired value for "some_integer", it is now easy to set a breakpoint in GDB at the line displayDebugMessage_("stop here"). shown in the above snippet. This should improve the ability to quickly to set a breakpoint in GDB around at a given time and point in the simulation.
