• introduce a check_retraction function to numerically check whether a retraction method is a (correct) retraction.
• introduce a check_vector_transport function to numerically check whether a vector transport is a (correct) vector transport.

Changed

• introduced a ManifoldsBaseTestUtils module to encapsulate common types and function definitions in different parts of the tests.
