rework geoserver configuration:-geoserver context is set to 'geoserver' by default, but can be reconfigured-data directory is set in the geoserver web.xml file (we have a template, set the value accordingly, then overwrite the deployed version in the geoserver webapp)...
change metacatconfigure.html to metacat-configure.html
Updated geoserver password help links
Rename geoserverconfigure.html to geoserver-manual-configure.html
Added header and footer sections that allow admin to log in as different user and to see user documentation.
Replace tables with css
Initial addition of geoserver password configuration page
