Feature #3318: Mercury UI improvements from ESIP feedback need to be addressed
Improve sorting components for returned results
There were two issues with the sorting capabilty for results:
1) alphabetical sorting by member node was incorrect. It is sorting by node id, rather than node name. It should always sort based on the field being display so as to not confuse the user. However, there's not a clear use case for MN sort. Remove it from the sort list.
2) Use a tooltip over on hover events for each sorting button that indicates how the sort is being done ('Sort member nodes alphabetically')
3) Change label of the "Date" to "Start Date" to better highlight usage.
