ANN New LP solver

[apete]

The new LP solver is now the default alternative (develop branch, version 55.0.0-SNAPSHOT).

Previously you had to set
model.options.experimental = true;
to use it. Now, if you continue to set that option, you'll get the old solver.

It'll be a while longer before v55 is released – still plan some refactoring/tuning/cleanup.

If you use ojAlgo to solve LP or MIP models, now is a very good time to build and test using a SNAPSHOT version.

The new solver already handles cases the old couldn't, scales better, and has great potential for future improvements.
