Create proper log files (maybe add flags for INFO, WARN, ERROR in web-ui and a log viewer) using the python logger library.

Frontend should use have the ability to config team name, target networktables IP (and maybe a checkbox to use a roborio ip), enable and disable mDNS, and other relevant networking settings.

Features including snapshot and eyedropper nneed a back end implementation of data pass-through for the client.

For ease of use and deployment, a raspbain/some raspberry pi compatible image with LemonLight preinstalled will need to be created so teams can simply flash the image to their pis to get started.

The process sender and receiver threads seem to be throttled by the GIL and fail on windows.

PEP-8 is nice.

Exposure and color balance for certain cameras including the RasPiCam require specific libraries to adjust. Support for common cameras needs to be added.

LemonLight needs proper documentation with full specifications and examples to make it easily adaptable to frc teams. ReadTheDocs RSTs could be a good option here?

Both shell script level watchdogs (see #4) and watchdogs within the python backend will need to be made to handle crashed processes and threads

Measure processing latency and networktables latency to be used for performance optimization and sent over NT for use by teams.

The entire process happens in one process at the moment and gets throttled by the GIL.

The back end will need to properly apply all of the preferences in the vpr format:

• area_max - Max percent of screen area for a contour
• area_min - Min percent of screen area for a contour
• aspect_max - Max width/length ratio for a contour
• aspect_min - Min width/length ratio for a contour
• blue_balance - ?
• calibration_type - ?
• contour_grouping - ?
• contour_sort_final - Order to sort the contours by
• convexity_max - Fullness upper bound - unknown units
• convexity_min - Fullness lower bound - unknown units
• cross_a_a - ?
• cross_a_x - x (coord ?) of contour "crosshair"
• cross_a_y - y (coord ?) of contour "crosshair"
• cross_b_a - ?
• cross_b_x - x (coord ?) of second contour "crosshair"
• cross_b_y - y (coord ?) of second contour "crosshair"
• desc - Pipeline description string
• desired_contour_region - ?
• exposure - Exposure of camera in ms
• hue_max - HSV H upper bound
• hue_min - HSV H lower bound
• image_flip - [0, 1] - whether the camera image should be fipped
• image_source - int describing camera image source -- maybe for static image tuning?
• img_to_show - index of the snapshot to use for static image tuning
• red_balance - ?
• sat_max - HSV S upper bound
• sat_min - HSV S lower bound
• val_max - HSV V upper bound
• val_min - HSV V lower bound
