NEW TASK: This is a version of UVMOD designed to put models in
a spectral-line data set. Each component has the usual
spatial parameters, but also a central channel and channel
width of the Guassian spectral line. The RR and LL
polarizations are allowed to be different and components may
be positive or negative.
Moved nowhere.
shouild be available in tomorrow's MNJ.
