/**
* Object Circular Mapper
* Allows to map an object value through little sized uint (uint8 or uint16), allowing to reallocate
* mapping when all values are used.
* This is used to map long values (CEntityIds for instance) that are expected to appear frequently
* in a stream with short keys, without making sure all values fit in mapping table.
* For instance, if using uint8 as mapping key, when all 256 values are used, previously used key
* 0 is remapped to the new object value that appears in stream and so on (reallocations are done
* circularly through key values). Mask value is for test purposes only, not to be changed!
