create a flask-service that collects data from the netatmo cloud api every 10 mins and puts that data 
into rrd graphs.
Example of the data coming from netatmo's service is in payload_dict.py.
I have registered this app at netatmo as 'GetNetatmoData v2'
Create the following rrd's, each for 1 day, 2 weeks, 1 year:
 - Outdoor: min and max temp, humidity, pressure
 - Wind: gusts as line, average as bars. the (rainbow) color of the bar represent the wind-angle
 - Bedroom: average temp, co2, humidity
 - Study: average temp, co2, humidity
 - Living: average temp, co2, humidity
 rrdfolder must be configurable.

The flask-service:
- has a route to allow to query the last available data: .../last/[rrd-name]/[name of data-point]
- has a route to get the rrd-graph ...graph/[rrdname][period]

create a html page that display all graphs and allows to switch between periods.
