Improvements to the formatting.summary_line() function, and the removal of the indentation.

The test suite summary is printed out even if not all of the test suite is run.

The Test_api_base tests requiring Scientific python are now skipped if not installed.

Another docstring fix.

Docstring fix for the __init__() method.

Updated the copyright.

Added __init__() to Test_scientific to skip all tests of this class if the module is not installed.

The method adds the tests to the status.skipped_tests list and executes the base class __init__()
method.

The RelaxTestLoader now skips tests if the are in the status.skipped_test list.

This is instead of the skip flag being set or not.

System and unit tests can be skipped is the skip flag is set inside the TestCase class.

Added an empty list to the relax status object to store info about skipped system and unit tests.
