Estimates the d of a composite.

1	dComposite(rxx, d_vec, wt_vec = rep(1, length(d_vec)))

`rxx`	A matrix of predictor intercorrelations.
`d_vec`	A vector containing d's for each predictor.
`wt_vec`	A vector containing the weights of each item in rxx.

A vector of correlation coefficients.

This is essentially the same function as solveWt().
