  <!-- JSON feed of Bedework events,
       Bedework v3.4.x, Arlen Johnson

       Purpose: produces an array of javascript objects representing events.

       Usage: call the JSON feed from an html file by embedding a script tag.
       Examples:

       The next four days (max days = 31):
       <script src="http://localhost:8080/cal/main/listEvents.do?days=4&skinName=json-list-src" type="text/javascript"></script>

       A range of dates:
       <script src="http://localhost:8080/cal/main/listEvents.do?start=2008-10-03&end=2008-11-02&skinName=json-list-src" type="text/javascript"></script>

       The next ten days limited by category (you can append as many categories as you like):
       <script src="http://localhost:8080/cal/main/listEvents.do?days=10&cat=Concerts&skinName=json-list-src" type="text/javascript"></script>

       Filters: Arbitrary filters can be sent to this stylesheet using the query
       parameter "setappvar=filter(somekey:somevalue)".  Group (creator) and
       location filters are included here, but you can add more under line 82.

       The next ten days filtered by a group (creator):
       <script src="http://localhost:8080/cal/main/listEvents.do?days=10&setappvar=filter(creator:agrp_Library)&skinName=json-list-src" type="text/javascript"></script>

       Object name: The json object name can be passed by adding
       "setappvar=objName(myobjname)" to the query string, allowing multiple
       json object calls on the same html page.  If objName is not supplied,
       the default name is "bwObject".  e.g.:
       <script src="http://localhost:8080/cal/main/listEvents.do?days=4&setappvar(objName=myobj)&skinName=json-list-src" type="text/javascript"></script>
