Log:
Update of the rotation matrix example in the intro chapter of the user manual.

The function is now in lib.geometry.rotations.euler_to_R_zyz().  The example 
has also been converted
to the lstlisting environment for better formatting.

 The \prompt{ds} object is a dictionary type which contains the multiple data 
pipes.  All of relax's packages, modules, functions, and classes are also 
accessible by import statements.  For example to create a rotation matrix 
from three Euler angles in the z-y-z notation, type:
 
-\begin{exampleenv}
-relax> alpha = 0.1342 \\
-relax> beta = 1.0134 \\
-relax> gamma = 2.4747 \\
-relax> from maths\_fns.rotation\_matrix import R\_euler\_zyz \\
-relax> from numpy import float64, zeros \\
-relax> R = zeros((3,3), float64) \\
-relax> R\_euler\_zyz(R, alpha, beta, gamma) \\
-relax> R
-\end{exampleenv}
