Documentaiton of restrictions of snaphots configuration

[fhg-isi]

I tried to run the default configuraiton but only for a single month intead a whole year:

snapshots:
  start: "2013-01-01"
  end: "2013-02-01"
  inclusive: 'left'

Then I got the error below.

=> Please include some hint in the documentation what time ranges are supported.

In the overnight example, a time span of one wee seems to be used:

snapshots:
  start: "2013-03-01"
  end: "2013-03-08"

and there is no error like "AssertionError: Need at least a full year of data (more is better)".

Why is that the case?
