Is this refined version of #558 ?
Can I close #558 after #671 merged ?

[jonesmz]

@redboltz No, #558 is a better approach, but not finished.

[redboltz]

Should I merge #671 ? Doesn't #671 disturb #558 ?

[jonesmz]

This PR will make #558 have merge conflicts, but I don't believe that this PR will make implementing #558 any more complicated.

#558 uses the "Trie" datastructure to handle mqtt subscriptions, which is substantially better than boost-multi-index. This PR will not change how #558 is implemented, so any merge conflicts are not a big problem.

[jonesmz]

The reason for this PR is to allow wildcard handling right now, until #558 is finished.

[redboltz]

I understand. Thank you for elaborating.
