    MoinMoin - BarChart Parser

    This parser is used to create bar charts based on CSS code from http://concepts.waetech.com/bargraph/.
    
    Syntax:
        {{{#!BarChart
           title
           name=value
           ...
        }}}
        
        {{{#!BarChart
           name=value
           ...
        }}}

    Parameters:
        title: the title of the bar chart
        name=value: name is used as description. The value is used to set the length of the bar. The sum of all values
                    is 100%. 

    Examples:
       {{{#!BarChart
       yellow=10
       blue=20
       black=50
       white = 90
       orange=10
       green=20
       }}}
       
       {{{#!BarChart
       Colors
       yellow=10
       blue=20
       black=50
       white = 90
       orange=10
       green=20
       }}}
