* Simplifies the Feature, by:

* negative.
* 3) Making sure any turns that are very close to one of the game's

* modifications described above can result in turns of 0.49999997 due to
* floating point inaccuracies, which should instead be set to 0.5).
* 4) Preferring small turns in opposite direction over large turns.
* 5) Ensuring all turns are in [-1.0, 1.0].
* 6) Setting any turns of -0.5 to +0.5, and turns of -0.0 to +0.0.
*
* The first modification will only be done for features that allow all
* rotations, and the second will only be done for patterns that allow

/**
* Given a list containing player index, from-pos, and to-pos as key, this cache
* can look up a cached list of active features that were active the last time
* that same index was used to compute a list of active features.
*
* Given a current game state, the cache will first use the key-specific
* footprint of the complete Feature Set to ensure that all parts of the game
* state covered by the footprint are still identical to how they were when the
* active features were computed and stored in the cache. The active features
* will only be returned if all parts of the game state covered by the footprint
* are indeed still identical.
*
* Note that the cache is not linked to any specific Trial or Context, or even
* to any specific full match of a game being played. Generally, we expect the
* majority of the cache to remain valid throughout a single playout, with small
* parts becoming invalid during a playout, and most of the cache having turned
* invalid when we move on to the next playout. However, it is possible that
* some parts of the cache remain valid over many different playouts (e.g. parts
* of a board that trained policies are very unlikely to make moves in).
*
* We keep a separate cache per Thread (using ThreadLocal), to make sure that
* different playouts running in different Threads do not invalidate each
* others' caches.
