Initial beacon finder implementation
Fixed up circle center indices
Merge remote-tracking branch 'origin/master' into beacon_finder
Improved blob detection for the circles in the circles grid for our type of images. Exposed a bunch of tunable parameters in the launch file and set reasonable default values.
Focal length and image sensor resolution are set from the incoming camera info, and updated parameters to work with the spiffy new beacon
New color name based sample detection node

This only publishes image space coordinates currently, 3-space
coordinates coming soon
Added 3d point outflow based on stereo disp and cam parameters
Handle monocular images
Node for projecting ray from monocular cam to ground plane
The z coord in the monocular vector should be 1.0 for downstream use
Launch for testing color name detection on the nav pair
Launch for testing color name detection on the search DSLR
More parameters
This now appears to place the center point correctly on the ground
Added ray_to_points to the CMake install
Increase buffer size for dealing with DSLR images
Merge remote-tracking branch 'github/beacon_finder' into level1_alpha
Merge remote-tracking branch 'github/color_name_blob' into level1_alpha
Cleanup beacon_detector CMakelists
Broke out ray_cast to separate function
