Agile-analytics

Bugfixes
* Works with pip 10+ now

Fixes the packaging yaks so v0.15.1 shows up in PyPI with all the features from v0.15

New features
When using DateAnalyzer or PartialDateAnalyzer you can provide a strategy argument to choose the most recent date when looking at a ticket's history instead of the oldest date. Example:
1. Ticket enters Committed state on Day 1
2. Ticket enters Started state on Day 6
3. Ticket re-enters Committed state on Day 7
4. Ticket re-enters Started on Day 11
5. Ticket enters Done on Day 18
The previous, and default, behavior would select: Committed = Day 1, Started = Day 6, Done = Day 18
The new, and optional, behavior would select: Committed = Day 7, Started = Day 11, Done = Day 18

New features
* Done date is now pulled based on the oldest done date, rather than the newest
