 * CONSTANTS - redefine these in your script to change the
 * behaviour of fetch_rss() currently, most options effect the cache
 *
 * MAGPIE_CACHE_ON - Should Magpie cache parsed RSS objects? 
 * For me a built in cache was essential to creating a "PHP-like" 
 * feel to Magpie, see rss_cache.inc for rationale
 *
 *
 * MAGPIE_CACHE_DIR - Where should Magpie cache parsed RSS objects?
 * This should be a location that the webserver can write to.   If this 
 * directory does not already exist Mapie will try to be smart and create 
 * it.  This will often fail for permissions reasons.
 *
 *
 * MAGPIE_CACHE_AGE - How long to store cached RSS objects? In seconds.
 *
 *
 * MAGPIE_CACHE_FRESH_ONLY - If remote fetch fails, throw error
 * instead of returning stale object?
 *
 * MAGPIE_DEBUG - Display debugging notices?

    Function: fetch_rss: 
    Purpose:  return RSS object for the give url
              maintain the cache
    Input:    url of RSS file
    Output:   parsed RSS object (see rss_parse.inc)

    NOTES ON CACHEING:  
    If caching is on (MAGPIE_CACHE_ON) fetch_rss will first check the cache.
    
    NOTES ON RETRIEVING REMOTE FILES:
    If conditional gets are on (MAGPIE_CONDITIONAL_GET_ON) fetch_rss will
    return a cached object, and touch the cache object upon recieving a
    304.
    
    NOTES ON FAILED REQUESTS:
    If there is an HTTP error while fetching an RSS object, the cached
    version will be return, if it exists (and if MAGPIE_CACHE_FRESH_ONLY is off)
