Added obstacle detection test script
Basic distance filtering, cv image output
Close to first pass at detection algorithm
Starting to separate display from internal representation
Added depth slicing for obstacles, some weird de-noising that might not really work that well
Slicing obstacle detection + display for demo
Changed final image output to update with obstacles instead of with camera
Added sample distance-averaging script (to use with distance.bag) and modified distance scaling in obs.py to set a static maximum range.
Added ability for distance calc script to handle (i.e. ignore) nan/inf
merge in delayed raw image display
First pass at distance calculation function in dist.py
Added comments to detection script
More changes to distance test script
Changed final pretty result to not be downscaled anymore
More tweaks to obstacle detection run speed
Finally got the image and disparity ACTUALLY sync'd
New package roscv2 because apparently that's what's needed for c++ stuff
OpenCV working in cpp
Got cv bridge working + subscribers up and running
Got scaled depth stuff working/displaying
