// YOU NEED TO EDIT THE VARIABLE proxyname (SEE BELOW) WITH THE DOMAIN
// FOR YOU INSTITUTIONS EZPROXY / LIBRARY PROXY ....
//
// Notes:
// Ezproxy (http://www.usefulutilities.com/) is a common proxy program used by
// university libraries to allow access to subscription based full-text in journals.
// This plugin adds the proxy domain to outgoing links from journal sites and NCBI PubMed
// (eg, like .ezproxy.lib.unimelb.edu.au).
// This allows users to automatically follow links through their institutional 
// library proxy for seamless access to journal fulltext (if they are subscribed). 
//
// Could be easily modified to work with other similar proxies like the CoralCDN ..
