twWhichColsEqual: twWhichColsEqual
In twMisc: Utility functions of tw

compares each column of X to column of Z and returns indices of equal columns

1 2	twWhichColsEqual(X, Z = matrix(rep(z, ncol(X)), nrow = length(z)), z = NA)

`X`	matrix
`Z`	Matrix with same numer of rows.
`z`	alternatively, specify only one vector, which each row of X is compared against

If both vectors contain NA's at the same position the vectors are regarded equal. This is different from which with ==, where any NA leeds to a FALSE
