This class, derived from the virtual class "CovRobust"
accomodates MM Estimates of multivariate location and scatter.
Objects can be created by calls of the form new("CovMMest", ...)
,
but the usual way of creating CovSest
objects is a call to the function
CovMMest
which serves as a constructor.

Can be computed by the internal function

For the tuning parameters of the underlying S-estimate see the slot sest
