Portal UI: make facets easier to understand for a newcomer

[izaslavsky]

Karen: · when I load, it isn’t clear how to use the faceted search. I click the gear icon and get something incomprehensible. It is only by accident that I click on the facet name and see the drop down. Can we add an icon indicating they accordion/expand out?

Possible steps: 1) remove the gear icon, 2) add an icon (eg triangle) to facets (as it was in the first version), 3) add a phrase "click on facets to expand"

Also: 4) rename "keywords" to "Original keywords", 5) make "All CINERGI facets" bold, 6) add "CINERGI" to indicate the origin of some facets (Domain, Material, Parameter)

For present:

• hide the settings.
• rename fields
• figuring out how to correctly add tooltips using dojo: https://dojotoolkit.org/reference-guide/1.10/dijit/Tooltip.html

Will update after reindexing finishes,
