   3     MoinMoin - BarChart Parser
   4 
   5     This parser is used to create bar charts based on CSS code from http://concepts.waetech.com/bargraph/.
   6     
   7     Syntax:
   8         {{{#!BarChart
   9            title
  10            name=value
  11            ...
  12         }}}
  13         
  14         {{{#!BarChart
  15            name=value
  16            ...
  17         }}}
  18 
  19     Parameters:
  20         title: the title of the bar chart
  21         name=value: name is used as description. The value is used to set the length of the bar. The sum of all values
  22                     is 100%. 
  23 
  24     Examples:
  25        {{{#!BarChart
  26        yellow=10
  27        blue=20

  29        white = 90
