Detailed Description

Allows to uniquely identify a pointer in the universe.

It is in fact a sha1 hash on the concatenation of:

The process part is an uuid instead of the process id, to avoid that on a single machine two different processes with the same process id (after a loop in the process ids) cause different pointers to have the same PtrUid.

A PtrUid models the concepts Sequence and Hashable (i.e. std::hash<PtrUid> is defined).

If QI_PTRUID_DEBUG is defined, to ease debugging the first number of the digest is deterministic inside a process (static counter starting at 0).
