/*XXX Added on to handle the IE issue.  We need to do things in window.onload
jQuery's docuemnt ready function isn't the answer, we need to run our
code with window.onload (see http://stackoverflow.com/questions/1081812/javascript-unspecified-error-in-open-layers for details).

Other Javascript from the collective.geo suite has been wrapped in functions,
but we'll need a better way to work around this.
