* fix chimera overlap python

* fix search to clear proper cache

* add Exhaustive

* restore NNlib

* comment out working tests (for now)

* fixed hamming tests

* fixed hamming_distance in search and tests

* fix testów

* uncoment all tests

* search chimera full passes

* fixed the chimera_pathological_Z2 test

* bugfix

* fix repeated function definitions

* comment out long tests

* moved gauges to experimental so that they dont stop release (feature is not ready)

* uncomment tests

* fix deps

* remove prints

* make tests pass again

* update exhaustive versions
