Ensured coordination dependent dispersion is on by default
Updated module description
Removed arguments for coordination dependence of repulsive term
Added data for parameterising total energy to dissociation curve
datasets
Included options for dissociation curve datasets
Began module to calculate total energy pair-by-pair rather than
term-by-term
Updated constructor after parameterisation
Updated to cache the total charge of an input file
Updated to include function to vary proportion of repulsion used with
atomic separation
Added support for pair-by-pair parameterisation
