Script Summary: Replaces column-sort links in Horizon Information Portal (library catalog software) pages by client-side sorting code.
NOTE: Since there is no general way to match HIP sites by URL, you must add an appropriate include pattern for your library's catalog system. Something like: http://your.library's.hip.server/ipac20/ipac.jsp*menu=account*
TODO: handle holds submenu properly! Since it has two tables, I'll have to redo the code. And I don't have any holds right now. Of course, if anyone wants to help out, contact me at ddawson at icehouse dot net.
