The limit_check() method has been added to the cone objects to determine if a point is inside or not.

Added a new cone type in the Pseudo_elliptic class.

The frame order and N-state model cone_pdb() methods now use the isotropic cone object.

The cone_edge() method now calls a function to obtain the maximum polar angle.

The cone_edge() arg 'angle' has been changed to 'phi_max_fn'.

Added a new module for holding class objects defining different cone types.

This currently contains the Iso_cone class with the simple method phi_max() to return the cone edge.

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.
