CMF ZWiki Installation script

This file is a CMF installation script for LatexWiki.  It's meant to be used
as an External Method. Compatible with the CMF quick installer, or to use
manually, add an external method to the root of the CMF or Plone Site that
you want LatexWiki registered in with the configuration:

 id:            cmf_install_latexwiki
 title:         
 module name:   LatexWiki.Install
 function name: install

Then call this method in the context of the CMF/Plone site, by visiting
http://SITEURL/cmf_install_latexwiki . The install function will execute and
give information about the steps it took.
