//! Abstract class for scoring object(s) of type ParticleIndex.
/** SingletonScore will evaluate the score and derivatives
    for passed object(s) of type ParticleIndex.

    Use in conjunction with various
    restraints such as IMP::container::SingletonsRestraint or
    IMP::core::SingletonRestraint. The restraints couple the score
    functions with appropriate lists of object(s) of type ParticleIndex.

    It is possible to call the various evaluate* methods directly, but
    this is not recommended as they do not ensure that Model invariants
    (e.g. ScoreStates) are preserved. Use a Restraint or ScoringFunction
    to score the model instead.

    Implementers should check out IMP_SINGLETON_SCORE_METHODS().
