-Network Server
---------------
-
-If you provide a wallart server in 
-`network-server.h`,
-the program will periodically fetch an image/animation from it,
-and display that image/animation.
-
-Because the fetch takes some time,
-one of the animation patterns actually shows progress of the fetch.
-It's the one with the four lights of the same color.
-After it's either succeeded or failed,
-it stays on that color for a while,
-so you can tell how everything is going.
-Here's what the colors indicate:
-
-Color it stays on | Status
---- | ---
-Blue | Unable to connect to access point
-Aqua | Some sort of problem initiating the HTTPS request (DNS?)
-Green | HTTPS server request failed (404 or similar)
-Yellow | Image download failed
-Orange | Everything worked!
-
-A happy setup will cycle through each color once,
-and then display orange for a while.
