Changes

• Added arctangent normalization function. Useful for heavy-tailed input features, since it models the CDF of the Cauchy distribution
• Added auction win probability example as a demonstration of modeling increasing functions

Changes

• [Breaking] there is no longer a separation between b-spline curves and b-spline embeddings. Everything is handled gracefully by one class - BSplineCurve.

Fixed and improvements

• Faster and less memory-allocation hungry B-Spline and Legendre evaluation
