    MoinMoin - MonthCalendarTopList Macro
    
    You can use this macro to generate a list of recent entries from 
     a MonthCalendar data structure.
    This is an addition to the MonthCalendar macro, so you should make
      yourself familiar with THAT one before trying to understand what this action
      can do for you.          

    Call this macro on a base page for a MonthCalendar.
    It will pack the contents of all tips you get when moving a mouse
     over some day entry into a simple, clickable list.

    Revisions:
    * unnumbered: original version by Mark Stier. 
    
    * 1.0
      * modification to make it work with MoinMoin 1.5
    * 1.1
      * added support of titles in the form:
        * = title =
        or
        * '''title'''
      * if no title exists, the page still appears in the list named Untitled
      * only the first title appears
    * 1.2
      * back to the previous behaviour allowing several titles
    
    
    Usage:
      [[MonthCalendarTopList(X)]]
      
      will display the last X days entries.
