shapely.ops.transform permits simple projections.

Transformations are done vertex-wise and conserve vertices, so don't
absolutely preserve the shape of input geometries.
Use izip instead of zip to access coordinate values.

zip copies, izip doesn't and is faster.
Fixed broken link in docs.
Merge pull request #37 from pelson/broken_link

Fixed broken link in docs.
Open files in 'r' mode, add uninstall notes to the README.
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
Merge pull request #38 from mwtoews/affinity

Updates to manual, and a few other tidbits
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

Specific improvements to Sphinx configuration
Fixed empty collection instantiation.
