Mostly minor bug-fixes

Working state tracking, without abstraction; included in exploit

Now uses a reasonable default meaning for state in state tracking (throws away used information)

This introduces an experimental/preliminary state tracking mode that is integrated into GA exploitation automatically (new states are exploited). Right now, it helps solve examples/maze

Fairly well tested, and has been mostly stable for some time. Recent bug-fixes have been either minor or to quite obscure/experimental features.

Adds support for various directed swarm options, and fixes some long-standing (and obscure) bugs in alpha conversion and other features.

Initial github release; usually released via pip

First version with working exhaustive check, decent tests and CI, consistent naming of tests
