Shape class abstract

The Base class of a shape.

A shape renders elements of tuples from their aesthetic encode values. It is the key of painting geometry marks. Besides, the shape it self is an aesthetic encode in Grammar of Graphics.

Shapes could be customized by extending its subclasses of different geometory types, or directly extend this class for the CustomMark. Customizing shapes extenses chart types.
