Container of UT users and their corresponding UT.

The data structure is a map which each key is a pointer to the UT user node. The corresponding value is a pointer to the UT node which serves the corresponding UT user node.

The member is redundant, in a sense that m_utUsers also stores the same set of pointers to UT users. This approach is taken to preserve the ordering of the node pointers in m_utUsers, which is difficult to be replicated as a map.
