relax release 1.0.5.

This release includes both added features and bug fixes. The Euler angle beta of the diffusion
tensor is now treated as a glide reflection when between pi and 2pi rather than a translation of the
space between 0 and pi. The glide reflection and translation symmetries of the spheroid and
ellipsoid diffusion tensors are now collapsed such that all angles are between 0 and pi, and the
simulated values lie pi/2 either side of the fitted value.

Removed some debugging code.

Bug fix.

The module signal is no longer imported into the interpreter. Only ValueErrors are caught when
there is a failure in converting the Rex values into floats.

Bug fix.

The ignore SIGINT statement has been removed to return the keyboard interrupt signal to the prompt.

The simulated Euler angles of the diffusion tensor now have their symmetries collapsed.

Bug fixes.

All three Euler angles are now properly wrapped between 0 and 2pi.

The glide reflection symmetry of the Euler angle beta (0 to pi and pi to 2pi) is now taken into
account.

The glide reflection and translation symmetries are now removed, hence the Euler angles will all be
between 0 and pi.

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.
