Created the Bmrb.test_bmrb_rw GUI test.

This incomplete test is based on the bmrb_rw.py system test script.

Completed the GUI interface for the bmrb.citation user function.

Fix for the bmrb.citation user function documentation.

The 'type' argument was not being described.

Debugging print out removal.

Created a new wizard GUI element for lists of lists of strings.

This is similar to the list of strings GUI element, but has been extended for list of lists. It is
now used by the bmrb.citation user function.

The element_string_list() wizard method now has all arguments converted to keyword args.

Abstracted out most of the String_list wizard element into the List base class.

This will allow different list types to be easily added.

Fix for the wizard GetValue() and SetValue() methods.

The GUI elements are in the self._elements dictionary!

The bmrb.citation GUI user function now uses the new wizard page string list GUI element.

Completed the wizard string list GUI element.

This control opens a dialog consisting of an editable ListCtrl that the user can input the text
into.
