in 1.0.10, we now create the replicate covariance as follows: maintain clonality as off diagonals. use sum of clonality and updated eps on main diagonal.  main diagonal initialized eps term, like in the 1.0.10, to use the eps that would be if the error was orthogonal to p. still use simple clonlaity to initialize the clonality term.
we now iteratively update the diagonals of the replicate cov matrix. rep cov off diagonals are current clonality estimates. on diagonals are sum of curr clonality and estiamte eps values. initial cs is the simple clonality. initial eps are based on a replicate 2-norms compared against initial cs, subject to assumption that eps is expected to be ortho to underlying p.
