The inverse of the standard deviations corresponding to the variance
function structure represented by `object' are returned.
.CS
varWeights(object)
.RA
.AG object
an object inheriting from class `varFunc',
representing a variance function structure.
.RT
if `object' has a `weights' attribute, its value is
returned; else `NULL' is returned.
