Make chart UI elements clickable

[GoogleCodeExporter]

Please make the chart UI elemenets clickable to support drill down type charts. 
 This should inlcude, at the minimum, the segments of a pie chart and the bars 
of a bar chart, but I would aim for a design that makes this as generic of a 
solution as possible.

This is an advanced feature that will probably be part of an eventual pro 
version.

That's fair.  I would definetely buy a royalty-free license if this were 
offered.

I made (most) chart element clickable - see the attached diff.

My approach does not work on vertical charts, and I didn't do the work for 
chart types that do not extend XYChart (for instance, pie chart elements are 
not clickable). Other than that, it works great. I tested bar charts (stacked 
and not), lines, scatters, etc and the combined charts.

Please take a look and let me know what you think of the approach. I'd love to 
improve this sufficiently to get it integrated into achartengine ASAP. Thanks!

Here's an updated diff, adding the SeriesAndPointIndex class that I 
accidentally forgot to include last time.

For a demo of this feature, launch the "Embedded Chart Demo", add some points, 
and click on them - a toast will appear telling you which one you clicked on. 
Long press also works.

Take a look at the code in org.achartengine.chartdemo.demo.chart.XYChartBuilder 
for an example of how to use this new functionality.

Thanks to Craig, this feature was added to XY charts and is now available in 
the open-source version.
Fixed in SVN rev. r226.
