Instrumented code for counting:
* added counters to addition in cohomology and ChainWrapper
* rips-pairwise-cohomology counts the maximum elements stored in the cycles
* added alphashapes3d-cohomology
* moved progress_display from DynamicPersistence to StaticPersistence

Subject: Incorrect sign_at() in UPolynomial<double>
Message-Id: <cd79223a108d3900-0-artemis@metatron>
category: kinetic
UPolynomial<double>::sign_at() reports -1 as the sign of -2*x + 4 at x = 2.
Should be 0.
