Write CPBarPlot class

[GoogleCodeExporter]

The CPBarPlot class is for plotting bar and histogram plots. It should support 
bindings and the data 
source pattern, and have APIs similar to the CPScatterPlot class.

It should be possible to plot multiple data sets in a single bar graph (eg with 
different colored bars 
for each set). Multiple data sets could probably be handled as multiple 
instances of CPBarPlot, each 
with some drawing offset. 

The data source should only need to supply the height of the bars, not the x 
values. The CPBarPlot 
class should have properties that can be used to determine the location of the 
bars in x (eg location 
of first bar and separation of bars).

It would be good to have an optional 'overlay' fill for bar plots. This would 
enable people to use images and 
gradients to make shiny bars, and the like.

I'm working on this now.

Just use a CPFill for the interior of the bars. That way you can use any color 
(including patterns), gradient, or 
image you want.
