Shape

--------------------
- Add shapely.ops.transform.
- Permit empty sequences in collection constructors (49, 50).
- Individual polygons in MultiPolygon.__geo_interface__ are changed to tuples
to match Polygon.__geo_interface__ (51).
- Add shapely.ops.polygonize_full (57).

-------------------
- Avoid circular import between wkt/wkb and geometry.base by moving calls
to GEOS serializers to the latter module.
- Set _ndim when unpickling (issue 6).
- Don't install DLLs to Python's DLL directory (37).
- Add affinity module of affine transformation (31).
- Fix NameError that blocked installation with PyPy (40, 41).

-------------------
- Add ops.unary_union function.
- Alias ops.cascaded_union to ops.unary_union when GEOS CAPI >= (1,7,0).
- Add geos_version_string attribute to shapely.geos.
- Ensure parent is set when child geometry is accessed.
- Generate _speedups.c using Cython when building from repo when missing,
stale, or the build target is "sdist".
- The is_simple predicate of invalid, self-intersecting linear rings now
returns ``False``.
- Remove VERSION.txt from repo, it's now written by the distutils setup script
with value of shapely.__version__.

-------------------
- Eliminate numerical sensitivity in a method chaining test (Debian bug
663210).
- Account for cascaded union of random buffered test points being a polygon
or multipolygon (Debian bug 666655).
- Use Cython to build speedups if it is installed.
- Avoid stumbling over SVN revision numbers in GEOS C API version strings.

-------------------
- A geometry's coords property is now sliceable, yielding a list of coordinate
values.
- Homogeneous collections are now sliceable, yielding a new collection of the
same type.

-------------------
- Fixed errors in speedups on 32bit systems when GEOS references memory above
2GB.
- Add shapely.__version__ attribute.
- Update the manual.
