This sets up all of the basic functionality that is currently listed on ChartD and includes ~90% test coverage for all of the files.

The 1.0 release can build charts with:

• Up to 5 datasets
• Different colors for stroke and fill for each dataset (including specifying dotted and dashed values)
• Specify if you'd like a PNG or SVG version of a chart.
• Easily encode arrays of Doubles as a base62 encoded string
• Support for every property publicly listed on ChartD's website.

Happy charting 📊
