Detailed Description

An Angle decorator is a simple container of four particles, together with an ideal value (in radians) for the angle, a multiplicity and a stiffness.

Note that multiple Dihedral particles can exist for the same set of four particles. (For example, the CHARMM forcefield allows for multiple dihedrals to exist with different multiplicities.)
