DualHashKey

An implementation of a 64-bit Dual-Hash-Key, strongly inspired by the Linux kernels dcache hashes.

The primary use-case is to use it as key-type for an ordered collection, implicitely making the collection hierarchical thru the DHK, allowing to quickly find subkeys and permit range queries.
