Expanded the alignment tensor object.

The 'tensor' and 'tensor_diag' objects are no more. New structures include:
A
A_5D
A_diag
eigvals
S
S_5D
S_diag
P
P_5D
P_diag

'Aii_unit', where i is one of x, y, or z has been renamed to 'unit_i'. 'rotation' has been renamed
to 'R'.

Additional modifications to the alignment tensor print out to show more information.

Modified the alignment tensor print out to be more compact.

Fixed the Euler angle conversion unit tests for the beta = 0 degeneracy.

Expanded the maths_fns.rotation_matrix.R_to_euler_zyz() docstring to document the beta = 0 case.

Bug fix for maths_fns.rotation_matrix.R_to_euler_zyz() for the case where beta = 0.

This uses the sub-matrix components of the z rotation to put the full rotation into alpha (gamma
is zero).

Added 8 unit tests for maths_fns.rotation_matrix.R_to_euler_zyz().

This covers the problematic Euler angles of 0.

Added 6 more unit tests for the new maths_fns.rotation_matrix.reverse_euler_zyz() function.

This gives better coverage of the problematic areas.

Added 3 unit tests for the new maths_fns.rotation_matrix.reverse_euler_zyz() function.

This checks the double reversion to see if the original angles come back.

Added a system test to catch bug #14872 (https://gna.org/bugs/?14872).

This is the unicode selection bug reported by Olivier Serve <olivier dott serve att gmail dott com>.

Fix for the bug_14872_unicode_selection system test.

The system test was creating a pipe called 'mf' in the setUp() method causing model selection to
fail. This pipe is now excluded.

Added the reverse_euler_zyz() function.

This converts forwards rotation Euler angles into reverse rotation Euler angles.

Fix for bug #14872 (https://gna.org/bugs/?14872).

This is the unicode selection bug reported by Olivier Serve <olivier dott serve att gmail dott com>.

The selection string is now converted to a normal string using str() if it is detected to be unicode.
