Sankey Charts for Traffic Movement

[winsmith]

When signals contain a location and a source or a location and destination, we can display the user streams in a Sankey Chart.

• [ ] Add Sankey as new Chart Type
• [ ] Prepare data for Sankey
• [ ] Allow switching between source and destination modes
• [ ] Allow setting custom field names for source, location and destination

The web SDK sends a url parameter and a referrer, so *location would be url and source would be referrer. Using this, the sankey chart can count how many signals have a certain string as referrer.
