The CustusX Math library, based on Eigen.
The math in CustusX should preferrably be done in terms of Eigen, http://eigen.tuxfamily.org/dox/
The core classes Vector3D and Transform3D have been reduced to typedefs of Eigen structures.

| typedef Eigen::Affine3d cx::Transform3D |
Transform3D is a representation of an affine 3D transform.
Transform3D is implemented using the Eigen library type Eigen::Affine3d, and extended with convenience methods using the Eigen plugin system.
Some of the extension exist for backward compatibility with the old inhouse Transform3D.
