decide how to scaling uncertainty

[arlin]

This is a design ticket. After the design is done, make another ticket for the implementation.

The results that we are returning from the portal are uncertain. How do we convey this? We could have some pop-up messages that either give a warning, or provide a friendly explanation that dates are uncertain and scientists sometime disagree by 2-fold on the dates of things.

If DateLife has some uncertainty methods, then we could put error bars on the nodes.

@LunaSare @bomeara I am assigning this to me for now but I hope we can have a discussion about how to do this once we get a few other things resolved.
