Flow View: Trend Lines

[aso1124]

Add a trend line view to the main flow listing.

Our current idea:

Is to have a segmented bar for each Stage, representing the aggregate stage status for the chunk of time represented by each segment.

The period for the trend line will be based on a static set of selections: e.g. 1 day, 7 days, 1 month
Each selection will result in a fairly coarse-grained set of segments: e.g. 1 day = 3 hours segments; 7 days = 1 day; 1 month = 5 days (or something like that).

Each segment can be clickable, taking the user into the playback mode for the period represented by that segment.

We are going to simplify the approach for the initial release:
Trendline will be a configurable setting on the Flow level.
It's a simple on/off
If on, the trendline will show above the stages (same as playback)
Trendline will show 7days and use 3 hour segments
Clicking a segment will open playback for that segment.
