split dc.css

[jeroen]

Currently dc.css contains a mix of chart layout and stuff specific to the example/demo. When it is included in an application without modifying, it results in side-effects.

Would it be possible to split this into two files? One general purpose dc.css that sets nice style defaults for classes .chart, .pie-slice, etc, and which can directly be included in applications? And then another one with stuff that is specific to your demo/examples?

Also, .chart is a very general purpose term. Maybe it would be better to do .dc-chart or add two classes .dc.chart. You could automatically add these classes to the element when the chart is initiated through dc.barChart or dc.pieChart.

Yeah, thats a good idea. Originally I created this css file mainly just for the example but as the library grows it is not realistic to expect user to recreate their own stylesheet from scratch. I will try to do that in 0.9 release.
