<p>An R interface to the Lawson-Hanson
  NNLS implementation of an algorithm
  for non-negative linear least squares 
  that solves the least squares problem
  \(\min{\parallel A x = b \parallel_2}\)
  with the constraint \(x \ge 0\) where
  \(x \in R^n, b \in R^m\)  and \(A\) is an
  \(m \times n\) matrix. 
  Also allows the combination of non-negative and non-positive
  constraints on \(x\).</p>
