  10     Overview:
  11 
  12     This is a simply Blog macro that utilises a javascript calendar and the Include macro to hack together a pseudo bwiki (blog/wiki).
  13     The calendar is used to choose the entries to show, the number of visible entries is controlled by the select control "max entries".
  14     The button to the left of "max entries" allows you to toggle between the two modes "Show All" and "Show Published".
  15      *  "Show Published" only shows those days that contain entries up to the given "max entries", from the chosen calendar date.
  16      *  "Show All" Show all the dates, previous to the chosen calendar date, up to a maximum of "max entries".
  17      This is the mode you  will need to use to enter new  blog entries
  18 
  19     Dependencies
  20      * Include
  21 
  22     To install:
  23      * Save this macro in your macros directory

  28      * <entries>    : the maximum visible number of entries
  29      * <maxEntries> : the maximum value that <entries> can be, this is used to restrict the web gui
  30      * <startDay>   : The start Day for the calendar
  31       * values      : "Su", "Mo", "Tu", "We", "Th", "Fr", "Sa"
