/************************************
TOGGLE SEARCH OPTIONS
Written by Ethan Gruber, gruber@numismatics.org
Library: jQuery
Description: This javascript file handles the dynamic search form
in the search and search results pages.  Some fields require
text boxes, some require the entry of integers to search a range,
and the remaining query solr and return unique facets and write
them to the drop-down menu.
