Title: Spline interpolation for line and area charts

Lighweight plugin for plotting line splines and area splines.

Uses bezier curves to connect the points, as explained [here](http://scaledinnovation.com/analytics/splines/aboutSplines.html) , computing the control points first.

Solves issue #305.
