Expand related fixes mentioned in #74 for EMPTY geometries
 - ops.transform now returns geometries that are empty, similar to fix for
   affine_transform; formerly this raised an exception:
   "AttributeError: 'Point' object has no attribute 'geoms'"
 - Add test cases for transform and affine_transform
 - Further PEP8 to affinity.py, ops.py
Restructure Operators and LineString tests into unittest framework
 - Avoid 'wkt' comparison in tests, since this will be tested elsewhere
 - Move relevant parts from Array.txt to test_linestring.py
 - Centralise numpy import for unittests to __init__.py; show version #
 - Misc PEP8 in linestring.py
Restructure Point.txt tests into unittest framework
 - Avoid 'wkt' comparisons in favour of 'coords[:]'
 - Move relevant parts from Array.txt to test_point.py
 - Several PEP8 changes to point.py, including use of 'isinstance' in
   place of type comparisons; remove unused 'ndim'
Restructure MultiLineString, MultiPoint and [Multi]Polygon to unittest
 - Add geometry.base.dump_coords helper function to so it can be used
   to inspect coordinates more portably than wkt; not sure if this is
   where it should be home to.
 - Remove Array.txt, since it has been split into other test_*.py files
Several changes to make an Ubuntu 10.04 (lucid) with standard packages work:
 - Reconfigure polygonize.txt into test_polygonize.py to skip old GEOS
 - Remove advanced 'POINT Z EMPTY' WKT read, which raises ReadingError on
   older versions of GEOS (not sure which)
 - Remove 'six' development requirement, which isn't used anywhere
 - Several changes to setup.py:
   - Improve unittest2 requirement message
   - Force in-place build for 'test' for testing speedups
Restructure several .txt tests to unittest framework:
 - GeoInterface.txt -> test_geointerface.py
 - IterOps.txt -> test_iterops.py
 - Operations.txt -> test_operations.py
 - Persist.txt -> test_persist.py
 - Predicates.txt -> test_predicates.py
 - attribute-chains.txt -> merged to test_polygon.py
 - dimensions.txt -> merged to test_polygon.py
 - linemerge.txt -> test_linemerge.py
 - wkt_locale.txt -> test_locale.py
 - cascaded_union.txt -> test_union.py
 - Also merged test_unary_union.py -> test_union.py
Don't rule out ndarrays by testing for truth.

Because "The truth value of an array with more than one element is ambiguous.
Use a.any() or a.all()". Closes #84.
