# This is a really simple HTTP server for displaying text to the 
# Pimoroni Micro Dot pHAT. Once the server is running:
#
#   http://127.0.0.1:8000/?
#    => clears the display
#
#   http://127.0.0.1:8000/?hello
#    => puts "hello " on the display
#
#   http://127.0.0.1:8000/123456789
#    => puts "123456" on the display
