0.4.1

• New Feature: Riesz s-Energy Method to generate a well-spaced point-set on the unit simplex (reference directions) of arbitrary size.
• New Algorithm: An implementation of Hooke and Jeeves Pattern Search (well-known single-objective algorithm)
• New Documentation: We have re-arranged the documentation and explain now the minimize interface in more detail.
• New Feature: The problem can be parallelized by directly providing a starmapping callable (Contribution by Josh Karpel).
• Bugfix: MultiLayerReferenceDirectionFactory did not work because the scaling was disabled.
