        This library provides convenient generic access to [GeoRSS](http://www.georss.org/) feeds.
        
        ## Installation
        `pip install georss-generic-client`
        
        ## Usage
        See below for examples of how this library can be used for particular GeoRSS 
        feeds. After instantiating a particular class and supply the required 
        parameters, you can call `update` to retrieve the feed data. The return value 
        will be a tuple of a status code and the actual data in the form of a list of 
        feed entries specific to the selected feed.
        
        **Status Codes**
        * _UPDATE_OK_: Update went fine and data was retrieved. The library may still return empty data, for example because no entries fulfilled the filter criteria.
        * _UPDATE_OK_NO_DATA_: Update went fine but no data was retrieved, for example because the server indicated that there was not update since the last request.
        * _UPDATE_ERROR_: Something went wrong during the update
        
        **Supported Filters**
        
        | Filter     |                     | Description |
        |------------|---------------------|-------------|
        | Radius     | `filter_radius`     | Radius in kilometers around the home coordinates in which events from the feed are included. |
        | Categories | `filter_categories` | Array of category names. Only events with a category matching any of these are included. |
        
        **Example**
        ```python
        from georss_generic_client import GenericFeed
        # Home Coordinates: Latitude: -27.5, Longitude: 153.0
        # Filter radius: 200 km
        feed = GenericFeed((-27.5, 153.0), filter_radius=200, 
                           url="https://www.qfes.qld.gov.au/data/alerts/bushfireAlert.xml")
        status, entries = feed.update()
        ```
        
        ## Feed Manager
        
        The Feed Manager helps managing feed updates over time, by notifying the 
        consumer of the feed about new feed entries, updates and removed entries 
        compared to the last feed update.
        
        * If the current feed update is the first one, then all feed entries will be 
          reported as new. The feed manager will keep track of all feed entries' 
          external IDs that it has successfully processed.
        * If the current feed update is not the first one, then the feed manager will 
          produce three sets:
          * Feed entries that were not in the previous feed update but are in the 
            current feed update will be reported as new.
          * Feed entries that were in the previous feed update and are still in the 
            current feed update will be reported as to be updated.
          * Feed entries that were in the previous feed update but are not in the 
            current feed update will be reported to be removed.
        * If the current update fails, then all feed entries processed in the previous
          feed update will be reported to be removed.
        
        After a successful update from the feed, the feed manager will provide two
        different dates:
        
        * `last_update` will be the timestamp of the last successful update from the
          feed. This date may be useful if the consumer of this library wants to
          treat intermittent errors from feed updates differently.
        * `last_timestamp` will be the latest timestamp extracted from the feed data. 
          This requires that the underlying feed data actually contains a suitable 
          date. This date may be useful if the consumer of this library wants to 
          process feed entries differently if they haven't actually been updated.
