/*
let's use this class as helper to format data.
An example of usage:
Ngcp.csc.formatter.timeSince('2016-10-13T11:14:12.274000000+02:00');

The return value is
- "seconds ago" if date within the last minute
- "minutes ago" if date within the last 5 minutes
- "x minutes ago" if date between 6 and 59 minutes ago
- "today at hh:mm" if date >= than 1 hour ago today
- "yesterday at hh:mm" if date was during yesterday's timeframe (from 00:00 to 23:59)
- "dd.mm.yyy at hh:mm" else

TODO better data
