Detailed Description

Abstract base class for calculating the distance from a reference configuration.

A reference configuration can either have a particular set of atoms in a particular given configuration or it can be that a particular set of colvars have a particular set of values. It could also be a combination of both. To allow all the posible permutations and in order make it easy to add new ways of calculating the distance we have implemented this using polymorphism and multiple inheritance. The following provides information on how to implement a new method for calculating the distance between a pair of configurations
