Adding Hector Gazebo Plugins Package. For now, i am adding the source, but i will later have to figure out how to add the package as a rosdep for our entire stack
Deleting duplicate package
Correctly adding SickTim3xx Package this time :)
Merged all my local code changes that i have not yet pushed to github. This does not include any gazebo model SDFs. Scipio Will be added here from my OSX partition since it was quicker for me to make it work there. rmc_simulation will be added to the Software_RMC repo separately.
added .gitignore for build and lib folder in gazebo_config.
Temporarily deleteing *.rviz ignore so i can push my super awesome rviz visualition arrangement
reverted to ignoring .rviz file types.
Adding Scipio's Gazebo Model v0.6
Merge pull request #1 from chicagoedt/development

merging from upstream
moves misc and calibration files in line_detection. Looks way cleaner now. Only stuff in src is actual code

removes pointcloud publisher in line_detector
removes warped_line publisher in line_detection launch file
launch file now displays compressed images in image_view
reads in backprojection training file using package path instead of hard-coded absolute path
fixes #21. line_detection publishes line_image as compressed jpg image and launch file image_view now displays it
renames line_detector to backprojectgrass-skeletonize and changes all references to it
removes cv_bridge as a dependency from line_detection package
