v0.4.1

This update adds a pre-trained model (trained on COFW) that achieves a state of the art average error of 0.072 (in percent of the inter-eye-distance) on COFW-test (a884b3f). (The model in our paper has an error of 0.073.)

Additional minor improvements:

• Added a custom CMake target so that the library headers show up in IDEs (42f9c7e)
• Added the debug solver as VerbosePartialPivLUSolver to the library (5f56b41)
• Fix: Added the missing verbose_solver header (2f85b13)
