Calculate known minimum or estimated entropy for survey vignettes

1	anchors.combn(adata, fdata, type, options)

`adata`	object of class anchors.data
`fdata`	data frame from which adata was built
`type`	either "B" or "C", specifying nonparametric method
`options`	object of class anchors.options

A list of class anchors.combn, containing elements

`vign.rank`	a matrix with columns corresponding to the vignette selection, the estimated entropy (if covar is specified), the known entropy, the number of cases with intervals for that particular vignette selection, and 2J+1 number of categories for the given vignettes.
`N`	the number of observations after list-wise deletion
`self`	a character string containing the variable name of the self-response question
`vign`	a character vector containing the variable names of the vignette questions. The first element of the vector corresponds to vignette 1, the second vignette 2, etc.
