Comparison UI for Attributes

There are times when the user needs to compare aspects of the simulation pre-processing information. For example, there maybe a set of model faces that user would like to know what mesh refinement sizes have been associated with them. Or a user may wish to compare the electrical conductivity between all of the materials that are currently defined.

The UI could look something like this:

Here the user specifies a query string that defines which information should be displayed.

Since these query strings can be complex, the designer should be able to add predefined queries and maybe have some form of query formation pallet?
