Removed the pipe test from the pymol.cone_pdb() user function.

This check is not necessary as a data pipe is not needed for this.

Fix for the N-state model user function n_state_model.cone_pdb().

This was not calling the correct method.

Bug fix for the N-state model cone PDB creation _cone_pdb() method.

The internal structural API had changed. structure.add_struct() is now called
structure.add_molecule().

Partially removed the need for Fink specific modifications.

This removes the need for the patch given by Jack Howarth <howarth att bromo dot med dot uc dot edu>
in the message https://mail.gna.org/public/relax-users/2010-02/msg00031.html.

A similar python specific path was being used to find Python.h on all architectures, so the include
path was copied and modified to be a bin path.

Removed the iteration count check in the test_opt_rigid_rand_rot() system test.

This number is different on a PowerPC chip with Mac OS X, even if the parameter values are
identical. This was identified by Jack Howarth (howarth att bromo dot med dot uc dot edu) in the
post https://mail.gna.org/public/relax-users/2010-02/msg00025.html.

Fix for the angles system test for the new folding of the spherical angles.

The spheroidal diffusion tensor major axis angles are now folded using angles.fold_spherical_angles().

Added default lower and upper bounds to fold_spherical_angles().

More epydoc tags have been added.

The fold_spherical_angles() performs a second wrapping in case the angles shift out of the window.

Window size checks have also been added.

Added a new function fold_spherical_angles() for removing symmetry from spherical angles.

This will be useful for future use of these angles.
