Changed implementation of WeightedRips to store simplex values (max distance between simplices' vertices) as an invisible layer on top of each simplex object, so that the data() field of WeightedRips has been freed for use by the users again.

Subject: Incorrect sign_at() in UPolynomial<double>
Message-Id: <cd79223a108d3900-0-artemis@metatron>

UPolynomial<double>::sign_at() reports -1 as the sign of -2*x + 4 at x = 2.
Should be 0.
