Bug #2207. Metacat Advanced Search interface.
Improvements to Advanced Search form:
(1) Delete keywordSearch() function. Not used in advanced search form.
(2) Re-initialize hidden form values for geographic boundaries.
(3) Change table width to 100% so horizontal rules will span the full width.
(4) Comment out input field that allows user to restrict search to a particular LTER site. This is only useful within LTER.
