consolidate topological tools

[marc-hanheide]

In disucssion today it became clear we need to consolidate the tools to create topological maps.

@ibrahimhroob, I think you were involved in BACCHUS, where there was a little tool to "poop" topological nodes, i.e., navigate the robot, and push a button (on the remote control?) to record the topological map?

Also, we have the rviz tools in the topological_navigation repository, and we have @arsh09's current work in https://github.com/LCAS/topoeditor

I have mainly assigned this to @ibrahimhroob, to consolidate all the tools we have (and document them).
