Specific improvements to Sphinx configuration:
- Reorder '..' in sys.path so the current source tree is imported first
- Remove ``from shapely import *`` since it does nothing
- Import modules used in code for pyplots, otherwise these are not visible (or an older implementation is used)
- Comment-out unused templates_path and html_static_path
Merge pull request #39 from mwtoews/affinity
