This class is meant to generate graphical
percentage bars made with star icons. It can be
used to present the results of poll systems on
which the generated percentage bars represent
relative values of each poll choice. The class
comes in two versions: one for drawing large stars
and another for small stars. Several presentation
details may be configured, like the star colors
and the number of stars to present for 100% bars.
The class generates the star bar images in PNG
format.
