// <synopsis>
// A rotation matrix is a 3x3 matrix, which can be used to rotate a coordinate
// system, notably the direction cosines in
// <linkto class=MVDirection>MVDirection</linkto>.<br>
// A RotMatrix can be constructed by the default constructor (which will
// set the diagonal to 1), a copy constructor, and from a set of
// Euler angles with <src>RotMatrix(Euler)</src>.<br>
// Multiplication can be done (by *= and *) of two rotation matrices.<br>
// The (uInt, uInt) operator returns the indicated element.
// </synopsis>
//
// <example>
// See <linkto class=Euler>Euler</linkto>
// </example>
//
// <motivation>
// To use in nutation and other coordinate calculations
