Fix/avoid empty occupancy grid when no subscriber #355

Closed PerrineAguiar closed 7 years ago

PerrineAguiar commented 7 years ago

This PR adds two ROS parameters to enable/disable mesh and occupancy grid. That way we avoid relying on the number of subscribers to extract and publish them.

Fixes #345.

@smits I added the check around the publish call.
