remove references to Jenkins
import PythonicTestCase library (MIT License) and add a test for XSD parsing of references
skip (failing) code generation tests: These don't work for a long time so let's skip them for now.
use "self.fail()" in tests instead of the clunky 'self.assertTrue(False, "Should not get here.")'
spelling in module docstring
remove useless empty docstrings
update included iso8601 module (MIT license, release 0.1.8)
reduce visual clutter by removing excessive empty lines and changing the separator comments
fix spelling in method name: "determin_soap_action()" -> "determine_soap_action()"
spelling/grammar fixes in docstrings
add test to check code generation with a very simple XSD mapping
raise exception with proper exception class.

Using strings as exception is ugly and deprecated: It probably kills kittens as well.
add tests for xsd.Ref rendering (including skipped tests for functionality which is currently not implemented)
implement xsd:Ref rendering when the reference points to a ComplexType (not a Group)
add some tests for rendering xsdspec.Element instances
add (currently skipped) test to check that an xsdspec.Element with a "ref" attribute does not accept incompatible attributes such as "name", "type", "nillable"
add tests for references to other elements (currently not implemented, hence the tests are skipped)
add some basic documentation about the state of the library, limitations and some strategies how to implement new features
