Renamed the propylene carbonate files to the correct name of pyrotartaric anhydride.

Added a PDB file and RDC values (and absolute J+D and J) for propylene carbonate.

This will be used for testing of pseudo-atoms in the N-state model analysis.

Created the pipe_control.mol_res_spin.pseudoatom_loop() function.

This is used to loop over the spin containers corresponding to a given pseudo-atom.

Created the pipe_control.mol_res_spin.is_pseudoatom() function to simplify pseudo-atom handling.

Shifted the RDC and PCS assembly methods from the main class to the data module for the N-state analysis.

The rdc.read user function will now skip all lines of the RDC file starting with '#'.

To include molecule identifiers at the start of the line will now require quotation marks.

Updated some ShereKhan language details in the dispersion software comparison table of the manual.

Added the TAP03 model to the dispersion chapter of the user manual.

The Arrhenius analysis is also performed by cpmg_fit.

This is for the dispersion software comparison table in the manual.

Updated the dispersion software comparison table for the optimisation in GUARDD.

I have added the 'MATLAB interior-point black magic' algorithm as MATLAB is not kind enough to
explain what algorithm it is really using.
