Initial CLI/GUI for operating the drones

[dennisss]

• Possibly write a simple GUI with some buttons in Qt
• We need to be able to hit 'Go'
• Hit 'Pause' (should stop at the next 'safe' location in the choreography velocity=0)
• If Paused, hit 'Land at current position'
• At all times, hit 'Kill'

All these should be commands while the server is running. Restarting the server to change arguments/configs is not an option.

Depending on our approach, related to #18

@dmz38 , it was suggested that maybe you would be interesting in heading this up so that we have a snappy thing to work with this weekend

[dmz38]

Acknowledging receipt of this ticket. Will have an HTML GUI for this weekend.

@dmz38 You might want to look at the Qt framework. We just need a really simple thing that can call C++ functions on button press.

[dennisss]

If Qt is too high of a learning curve, almost anything will work. I can strap in a generic message passer like lcm/zcm which supports JavaScript/c++

Global status things

• Mocap connected
• Playing state
• Time

Useful things to have in a per drone status list:

• Tracking Active
• Connected
• Armed

[dmz38]

Array of string log messages for each drone, to be able to see what is going on for each.

[dennisss]

Also, probably most useful of all, a battery monitor per drone showing percentage and current floating point version.

@dmz38 This task has a lot of pieces. For any requirement that isn't done by tomorrow, please either make a new issue or contact me privately so I can make issue(s) for the remaining requirements unaddressed in this issue and assign it a milestone asap.

[tessmichi]

@dmz38 Did you separate this into multiple tasks or do we still need to do that? I'd like to close this one huge one and replace it with smaller bite-sized tasks that can be assigned to whichever due date best fits

[tessmichi]

^he is currently working on this so we can close this issue and open the new ones

[dmz38]

Created #67 #68 #69 #70 #71 to replace this ticket. Closing because now duplicating these individual action items.
