Blync Studio Light

go based CLI to set Blync light based on calendar or manual interaction.

here is a picture my daughter drew to explain.

I hang my light outside my home office to convey to family if they can visit.

Red means don't go in, sad daughter. Green means it's ok to visit daddy, happy daughter!

Light updates based on free/busy events.
