When we click on a datatype, the overlay with details opens up.
There, we currently display only the Generic Metadata fields.
We should support the display of Scientific Metadata, as we had on TVB 1.5.8 (see demo).
I think we used to display there the summary_info() from each datatype. But since that is on the library side, we should figure another solution. Maybe have something similar to summary_info() on the indexes.
