PerturbParticleType

class PerturbParticleType : public feasst::Perturb

Change the type of a Particle. If the Particle has multiple Sites, then fix the coordinate of the first site of both particle types to be equal, and then randomly rotate the rest of the sites according to the positions given in the fstprt file particle type definition (e.g., this only works properly for rigid molecules, not flexible ones).
