Suds Python library request construction related unit tests.

Suds provides the user with an option to automatically 'hide' wrapper elements
around simple types and allow the user to specify such parameters without
explicitly creating those wrappers. For example: function taking a parameter of
type X, where X is a sequence containing only a single simple data type (e.g.
string or integer) will be callable by directly passing it that internal simple
data type value instead of first wrapping that value in an object of type X and
then passing that wrapper object instead.
