merged commit
Added launch file parameters for the table top voxel size, observation voxel size and a parameter for the point distance cutoff. Also added a parameter to specify whether to update the metarooms with new room observations
Saving dynamic clusters in the room xml file and as a pcd file
Saving pcd files only if they don't exist already (only for rooms, not for metarooms)
