Manually localise in RTAB-Map

[rakshak]

Is there some way to manually localize on RTAB-Map?

At the moment, when we launch RTAB-Map in localization mode, we need to drive the rover account for a bit until it finds enough visual points to localize.

Is there some way to manually localize on the map so we don't have to wait (an undetermined amount of time) for the rover to figure out where it is on the map?
