552    
553    Merge table rows together. This will merge a table so that adjacent cells with the same content will only be shown once.
554    
555    Something like this:
556    
557        -----------------------
558        |    1     |    a     |
559        -----------------------
560        |    1     |    b     |
561        -----------------------
562        |    2     |    c     |
563        -----------------------
564        |    3     |    d     |
565        -----------------------
566        |    4     |    d     |
567        -----------------------
568        |    5     |    d     |
569        -----------------------
570    
571    Will become:
572    
573        -----------------------
574        |          |    a     |
575        |    1     |-----------
576        |          |    b     |

1345    Add something to the RSS feed. The rss feeds are stored in the Html directory, and there are several RSS feeds:
1346            SEED.rss                - everything gets written here
1347            SEEDgenomes.rss                 - whenever a genome is added to the SEED
1348            SEEDsubsystems.rss      - whenever a subsystem is edited (or should this be added?)
1349    
1350    
1351    RSS feeds must contain a title, description, and link. The title is what is seen e.g. from the firefox or safari pull down menu. The description is seen from within an rss aggregator, and may be displayed on web pages and so on.
1352    
1353    The method takes a reference to an array containing the file names for the RSS feeds to add your item to, and a hash of items for the xml. Only title, description, and link are required tags in the XML.
1354    
1355    The file names are the full name of the file, eg SEEDsubsystems.rss, SEEDgenomes.rss. Be aware that this is a file name, though, so don't uses special characters. The path will be added.
1356    
1357    The has can have these keys:
1358    
1359    REQUIRED:
1360    title       : the title. This is usually what is seen by the user in the pull down menu
1361    description : a more complete description that is often seen is rss viewers but not always
1362    link        : link to the item that was added/edited
1363    All other keys are treated as optional RSS arguments and written to the file.
1364    
1365    At most, $max_entries recent entries are stored in the rss file, and this is currently 50.
1366    
1367    RSS files are quite simple, and contain some standard header information, and then individual items surrounded by an <item> </item> tag. Note that there is also an initial title/description/link set that describes the file.
