/**
 * Calculates the rank-revealing QR-decomposition of a matrix, with column pivoting.
 * <p>The rank-revealing QR-decomposition of a matrix A consists of three matrices Q,
 * R and P such that AP=QR.  Q is orthogonal (Q<sup>T</sup>Q = I), and R is upper triangular.
 * If A is m&times;n, Q is m&times;m and R is m&times;n and P is n&times;n.</p>
 * <p>QR decomposition with column pivoting produces a rank-revealing QR
