Detailed Description

template<class T>
class KisTileHashTableIteratorTraits2< T >

This is a template for a hash table that stores tiles (or some other objects resembling tiles). Actually, this object should only have col()/row() methods and be able to answer notifyDetachedFromDataManager() requests to be stored here. It is used in KisTiledDataManager and KisMementoManager.

How to use: 1) each hash must be unique, otherwise tiles would rewrite each-other 2) 0 key is reserved, so can't be used 3) col and row must be less than 0x7FFF to guarantee uniqueness of hash for each pair
