(protovis) Changed the way the Dot shape applies the aspectRatio.
It used an svg scale transformation, but this has the disadvantage of distorting borders as well.
Now each shape's drawing code takes the horizontal and vertical radius directly into account.

[CDF-225] - Review CCC site and examples build.
* Added build and test commands information to the readme file
* Fixed the path of the CCC build output in the generateSite shell script
[ANALYZER-1545] - Ability to show data labels on charts and visualizations.
* Added a new plot pvc.visual.Plot option, "ValuesOverflow", with values "show", "trim", and "hide" (the later is the default).
** The option is currently supported by the chart types: Bar, NormalizedBar, Waterfall, Pie, Treemap and Sunburst.
* Fixed regression of pvc.BarAbstractPanel#pvBarPanel field; was pointing to the CCC Sign object, instead of to the corresponding pv.Mark.
* Fixed regression of bar-family charts' and of the pie chart values label, that would become hidden for certain unrelated configurations.
* Removed the pvc.visual.SunburstPlot's "SubValuesVisible" option, created to satisfy an Analyzer use case, but that can equally and better be handled on the ccc_wrapper.
* Improved the valuesOptimizeLegibility option, by only applying it when the label is considered inside the associated visual element.
* Update to latest protovis, containing related changes.
[ANALYZER-1545] - Ability to show data labels on charts and visualizations (Docs and Examples)
