[Feature Proposal] Display multiple data sets and fits together

[MonsterBoyLives]

Many times we are required to plot similar data sets (and their fits) together, similar to plot overlay. For example, the relation between voltage and current at different temperatures. We imagine loading many data sets, plotting them + any number of fitted function. An example of the desired output is attached in the screenshot: two different data sets, with different fits, are displayed together.

First, I agree that this is an important ability that should be supported in a future version of Eddington-GUI.

However, this is a big change in the Eddington-GUI workflow: at the moment, Eddington-GUI is designed to work with a single data file at a time, and changing that means a big change in the user experience of the software.

At the moment, I add this ability to the 0.1.0 release milestone, since it is a huge change.
We may consider pulling it sooner if we could find a way to make that ability possible within the current workflow.
