ported r2634,r2636 & r2716 to the test-suite branch, corrected
test_float.py

commands used
svn merge -r2633:2634 svn+ssh://varioustoxins@.../svn/relax/1.2
svn merge -r2635:2636 svn+ssh://varioustoxins@.../svn/relax/1.2
svn merge -r2715:2716 svn+ssh://varioustoxins@.../svn/relax/1.2

these changes add the ieee-754 nan/inf code and nan catching from branch 1.3

reversed merge of ported r2634,r2636 & r2716 in r2717 to separate them
from the patches to float.py

Spell check of the PDB and PyMOL user functions and generic_fns code.

Added extra atoms to the 'AXS' residue of the tensor PDB representation for labelling.

Two or six extra atoms are added for the spheroid and ellipsoid axes respectively. These are set to
be nitrogen atoms to allow easy selection of just those atoms. They are also placed 3 Angstrom
outside of the geometric object so that the labels do not clash with the latitudinal and
longitudinal lines as well as the Monte Carlo simulation axes.

The code for generating the PDB chemical formula in 'self.write_pdb_file()' was modified to handle
nitrogen atoms.

The PyMOL user function 'pymol.tensor_pdb()' has been modified to use the new representation. The
final selection is also deleted at the end of the user function.

'pymol.tensor_pdb()' has been modified to change the representation of 'COM', 'AXS', and 'SIM'.

The centre of mass 'COM' is shown as the 'dots' representation and is coloured blue.

The diffusion tensor axes 'AXS' are shown as the 'sticks' representation, is coloured cyan, and the
atoms labelled to show 'Dpar', 'Dx', 'Dy', and 'Dz' in PyMOL.

The Monte Carlo simulations axes are coloured cyan.

Added a description of the 4 residues 'COM', 'TNS', 'AXS', and 'SIM' to 'pdb.create_tensor_pdb()'.

Removed the unused arguments to the 'self.write_pdb_file()' function.
