Add support for data-driven unittests.

Makes it possible to parameterize a unittest test case method
and provide several sets of values for those test parameters so
as to execute that test for every set of data provided.

A test method needs to be named with the "ddtest_" prefix instead
of the unittest standard "test_" prefix to distinguish it from
regular unittest test case methods.

A test method needs to be decorated with the "data_driven_test"
decorator, and a dataset source provided to the decorator.

The unittest.TestCase class containing data driven tests must be
decorated with the "DataDrivenFixture" decorator.

Adds a unittest.TestCase class decorator, "DataDrivenFixture", to
apply the test multiplication logic.

Adds a test method decorator, "data_driven_test", to define the
datasource a data driven test will use, and denote that test as
a data driven test.

Adds a Dataset object, a class that defines a dictionary
to hold the keyword argument values for a data driven test, and
the name of the dataset itself.

Adds a module, "datasets.py" that defines several classes for
providing various user-defined and generic datasets to data driven
tests via list-like iterators.

Adding default content-type header

As a general rule, I believe that for the majority of cases, the "Content-
Type" header parameter should reflect the serialize format.

Subject: Refactor runner. Change verbosity. Fix supress load
tests.
The runner is still a work in progress.
cleaned up some of the logic. added a -d option to
send arbitrary data (key=value) to the tests in order to do
things like turning skipIf's and skipUnless on and off or
turning debug statements on and off. verbosity has changed.
-v 0-3:
0 the number of fail, error, skipped.
1 is dots and the number of fail, error, skipped.
2 is method and the number of fail, error, skipped.
3 is the method, comments, and the number of fail, error, skipped.
worked the json file generation into the refactor.
changed the command line option for json result to True/False
and changed the check for the flag where it is called

fixed supression of load tests
added the changes to the fixture that make the runner changes
to verbosity work
