warn when trips per day or week changes a lot

[GoogleCodeExporter]

a few people have complained that they don't get a warning about feed
expiration when a single service_id is ending soon but other service_ids
continue. We can't add a warning when any single service_id expires because
some feeds, for example merged feeds and those that cross a schedule
change, have a legitimate need for ending service_ids. Instead we should
warn if there is a big change in trips per day or week within the upcoming
weeks. A graph of this in the validation html would be nice too.

issue 188 "Detect weeks without service" is a partial fix for this. Maybe it 
should be 
generalized to look for pairs for 14 day periods with drastically different 
number of 
trips.

Issue 70 is about displaying a summary. This issue is about automated detection 
of suspicious patterns.
