Faster specialized simulators available

A set of three specialized simulators are now available, for the black-oil + solvent, black-oil + polymer and two-phase water + oil cases.

They are available on GitHub, and you need to build from the latest OPM master branches to get them. Their functionality will be part of the next OPM release (in October) if you prefer to install binary packages. The simulator programs are called flow_ebos_solvent (replacing flow_solvent), flow_ebos_polymer (replacing flow_polymer) and flow_ebos_2p.

Performance of the new simulators is significantly better than the existing ones, especially the specialized two-phase simulator.

It is our goal to incorporate all of these specialized simulators in a single Flow executable, which automatically will select the best variant to run each case.
