Gazebo slam

[jinsooPark-17]

Testing a larger gazebo map that reflects GDC 3ne better.

• doors_map.pgm, doors_map.yaml and doors_map_corpp.yaml remains unchanged.
  If those files are also needed to be changed, please contact me.

You mentioned those files are unchanged, doors_map.yaml and doors_map_corpp.yaml have been altered with the same minor changes. doors_map.pgm has minor changes as well, but I'm not sure what they are.
Do they need their new value?

Also, can you revert the README to how it was before?

@YuqianJiang since you use the segbot simulator regularly (I think?) I've added you as a reviewer as well

[jinsooPark-17]

I revert Readme.md to that of the master branch.

Sorry for the confusion. I uploaded a larger but incorrect version of 'doors_map.pgm' and other files.
If someone needs those files, then one has to create doors_map.pgm & doors_map.yaml file based on the new 3ne.pgm file and door configuration of the new Gazebo world.

After discussing it with @YuqianJiang, the best way to move forward integrating this world is to add it as a separate world, rather than replacing the existing world. This is to help keep consistency for people that have used the 'standard' simulator for their experiments in the past.

So this entails the following changes:

1. all the 3ne.yaml and 3ne.dae and 3ne.pgm etc should be renamed to something like 3ne_scaled and get its own folder in utexas_gdc/maps/simulation/.
2. The old 3ne.* files should be replaced with what is on the master branch.
3. The simulation launch file(s) should be modified as appropriate to launch this new world.

You can see this PR to see an example of how I added an argument to the highest level of launch file, that then trickles down to launch the desired Gazebo world launch files which lives in the bwi_common repository. This does mean creating a separate branch in the bwi repository, and creating another PR there.
