Detailed Description
template<typename KeyHashFunctorT = KvdsPageMapDefaultKeyHashFunctor>
class moost::kvds::KvdsPageMapNonIntrinsicKey< KeyHashFunctorT >
*** This class is NOT thread safe ***
A non-intrinsic type pagemap, which uses the default key hash functor (above). If you're not too worried about performance and/or memory usage then this provides a nice simple way to get up and running with the KVDS Page Store. If you wish to provide a specific pagemap that is customised for your specific key types you can do so by createing your own custom pagemap class. This is the default page map unless you specify another.

Allow the client to apply any specific settings to the underlying storage. We need to do this to ensure the interface of each storage is consistance and yet different stores may have different requirements. For example the sparse hash map needs a call to set_deleted to allow deletions.
