v.1.0.1

Improvements:

1. Events saving method was changed to POST. The success status code is now 201.

2. Statistics request validation was added.

3. For GET “/events” request the default time limits are now applied only if no time filters were specified. The current datetime is set as an upper boundary and the current datetime minus the month as a lower excluded boundary. They are set if no time filters are specified in the request.

Bugs fixed:

1. Statistics requests with tags as target or/and filter were fixed.

2. The “create_time” validation field in input events was fixed.
