One function has been created to wrap the Euler or spherical angles and remove the glide reflection
and translational symmetries.

Bug fix.

In the calculation of the Hessian of the ellipsoid correlation times, the factor data.R**3 caused
an OverflowError when Da was 0.0.

relax release 1.0.5.

This is a bugfix release, improving the user function 'diffusion_tensor.init'. This fixes problems
when using the ellipsoid parameters Dx, Dy, and Dz.

Bug fix.

Fixed problems with the 'diffusion_tensor.init' user function for the ellipsoid parameters Dx, Dy,
and Dz.

Updated the manual.

relax release 1.0.4.

This is a feature release. Significant improvements to the OpenDX mapping functions have been made,
including the ability to map any three parameters of all models within any order. Significantly
diffusion tensor parameters can now by mapped.

The 'axis_incs' integer can now be changed using the user function 'dx.map'.

Improved the axis labels of the OpenDX plots for diffusion tensor parameters.

Added the functions 'return_conversion_factor' and 'return_units' to the generic diffusion tensor
class.

Bug fix.

Was selecting elements of a list using round brakets.

Addition of the generic 'diffusion_tensor.set' function and bug fixes.
