pmemd and sander support a limited set of "extra points", but these are really
only documented in the code itself. See the define_frames() routine in
extra_pts.F90 in sander. You can see if what you want fits one of the
existing models, or add new types of extra points by modifying the code. There
is no user interface for defining new frames (i.e. new types of extra points.)
