Updates to manual: (first savepoint)
 - fix typos and remove trailing space
 - Consistancy of starting word "Returns" in docs
 - Add some PEP-8 to affinity module
 - Start documenting affinity module
 - Add math to documentation, with pngmath
savepoint 2:
 - added other functions from affinity, need to add examples next
 - minor adjustment to ``interpret_origin`` logic
 - use |revsion| and |today| in manual.txt, so they are always good
oops, revert changes to ``interpret_origin``
- Include plot examples for rotate, scale and skew
- Enumerate Figure numbers manually
- Make punctuation for figures consistent "Figure X." (previously it was mixed with "Figure X:")
- Add a few items to .gitignore
- Use BLUE and GRAY docs/code/figure.py colors in other scripts
- Fix range(float) error in a[xy]_range for Python >2.6
- Remove Shapely wiki link, since it is no more (unless I'm missing something)
- Fix link to example apps
- Other URL fixes
- Delete HTML version of manual from docs/ since it is not current
- Clean up named affine transform examples a bit, and add source code to manual
Indent directives that do not have other basic sections for themselves
