'''
Bhorunicornhat
v0.7.0

A library to replace unicornhat and unicorn_hat_sim to use
any unicorn hat python script with a bhoreal or a Launchpad mini.

2 things to do :

1/ Change import in a unicorn target python program 

import unicornhat as unicorn

by :

import bhorunicornhat as unicorn

2/ Set target (bhoreal or launchpad) by calling unicornhat.dest(device,rotation) 
or modify destination and rotation manually : see a few lines down.
