/** Potential Registry.
 *
 * The Potential registry is a storage for any EmpiricalPotential instance to
 * be retrieved by name. It is a singleton and can be called from anywhere.
 *
 * This class is meant for convenience when loading and saving potential files.
 * By the keyword given in the potential file we may look up whether the
 * potential exists and modify it or create a new one accordingly. When saving
 * the present potentials to a file, we just have to iterate over all present
 * ones.
