This class is a specialized TProcessID managing the list of UUIDs.

In addition to TProcessID, this object has the following members:

fUUIDs : a THashList of TUUIDs in string format (using a TObjString)
fActive : a TBits table with one bit per TUUID in the table

When a new TUUID is entered into the list fUUIDs, it is assigned the first free slot in the list of bits and the TUUID UUIDNumber is set to this slot number.

When a TUUID is removed from the list, the corresponding bit is reset in fActive.

The object corresponding to a TUUID at slot I can be found via fObjects->At(I).

One can use two mechanisms to find the object corresponding to a TUUID:

the input is the TUUID.AsString. One can find the corresponding TObjString object objs in fUUIDs via THashList::FindObject(name). The slot number is then objs->GetUniqueID().
The input is the UUIDNumber. The slot number is UIUIDNumber

When a TRef points to an object having a TUUID, both the TRef and the referenced object have their bit kHasUUID set. In this case, the pointer TProcessID *fPID in TRef points to the unique object TProcessUUID. The TRef uniqueID is directly the UUIDNumber=slot number.
