Detailed Description

Euler_explicit angle class.

Rotations are generally handled through the clipper::Rotation class. This class only exists for conversion purposes.

This particular class represents three angles of rotation around specified axes e1, e2, e3 defined by their direction cosines ie rotate about e3, then e2, then e1

R = R(e1, phi1) R(e2, phi2) R(e3, phi3)

where R(e, phi) is the rotation matrix for a rotation by angle phi around axis e
