Added the relax 3.3.3 manual to the repository.

Updated the version number to 3.3.3.

relax version 3.3.3.

This is a major feature and bugfix release. It fixes a failure when loading relaxation data, adds
Python 3 support for using the NMRPipe showApod software, and Python 2.5 fixes for the
align_tensor.display user function. Features include a large expansion for the
align_tensor.matrix_angles and align_tensor.svd user functions to support the standard inter-matrix
angles, the unitary 9D vector notation {Sxx, Sxy, Sxz, Syx, Syy, Syz, Szx, Szy, Szz}, and the
irreducible spherical tensor 5D basis set of {A-2, A-1, A0, A1, A2} for correctly calculating the
inter-tensor angles, singular values and condition numbers.

Set up many redirects for the relax HTML manual at http://www.nmr-relax.com/manual/index.html.

This is required as the latex2html program used to build the manual has been modified to not
excluded the 'common words' from the page titles (see docs/devel/latex2html/). These redirects are
linked from outside, or in the relax API documentation.

Modified the Frame_order.test_pdb_model_iso_cone_z_axis system test to have a cone angle.

The cone opening half-angle was previously 0.0. The test now checks the geometric object in the PDB
file for a cone opening half-angle of 2.0.

Modified the Frame_order.test_pdb_model_iso_cone_xz_plane_tilt system test to have a cone angle.

The cone opening half-angle was previously 0.0. The test now checks the geometric object in the PDB
file for a cone opening half-angle of 2.0.

Created the Frame_order.test_pdb_model_pseudo_ellipse_xz_plane_tilt system test.

This checks the PDB file created by the frame_order.pdb_model user function for the pseudo-ellipse
model with a xz-plane tilt. To properly construct the coordinates, the rotate_from_Z() method was
modified to accept a rotation matrix argument to allow the geometric shape to be rotated.

Fixes for the checks in the Frame_order.test_pdb_model_* system tests.

Atomic positions are now checked with self.assertAlmostEqual() to 3 places, and the residue and atom
names and numbers are checked with self.assertEqual().

Created the Frame_order.test_pdb_model_pseudo_ellipse_z_axis system test.

This demonstrates the correct atom coordinates in the PDB file created by the frame_order.pdb_model
user function for the pseudo-ellipse model along the z-axis.

Fixes for all of the Frame_order system tests - the temporary directories are now being deleted.

The system test base class tearDown() method is now being called to properly clean up after the
tests.
