Title: Add 'gouraud' shading option to tripcolor.

This adds a basic shading='gouraud' option to tripcolor.

For a demonstration, take tripcolor_demo.py and replace shading='faceted' with shading='gouraud'.

I'm not very familiar with how collections work, so there is no support for offsets or transformations.
