Trolli Schmittlauch 18bdcce266 re-implement NodeCache data structure to emulate ring properly
- previously, there was at least 1 gap in the identifier ring
- now use normal integer comparison again, but forward lookups using
  proxy entries at the ID space boundaries
- wrap cache operations to properly handle proxy elements
- fix all previously working tests
- document choice of cache data structure
