+%   This function fits a 3D Morphable Model to landmarks in an image.
+%   It fits the pose (camera), PCA shape model, and expression blendshapes
+%   in an iterative way.
+%
+%   Please see the C++ documentation for the description of the parameters:
+%   http://patrikhuber.github.io/eos/doc/ (TODO: Update documentation!)
+%
+%   NOTE: In contrast to the C++ function, this Matlab function expects the
+%   morphable_model, blendshapes, landmark_mapper, edge_topology,
+%   contour_landmarks and model_contour as *filenames* to the respective
+%   files in the eos/share/ directory, and not the objects directly.
