//! An example singleton modifier
/** A simple singleton modifier which ensures the x,y,z coordinates
    stay in a box by wrapping them.

    Such a class could be coupled with an IMP::core::SingletonConstraint
    or IMP::container::SingletonsConstraint to keep a set of particles
    in a box.

    The source code is as follows:
    \include InternalCoordinatesConstraint.h
    \include InternalCoordinatesConstraint.cpp
