Knot theory

Review the existing features in Sage (anything) and elsewhere, and create some tickets of achievable features in the mid-run

• As we see here, http://ask.sagemath.org/question/8255/knot-theory-and-sage/ there is demand for this.

• Older ideas for many topological things are here http://wiki.sagemath.org/topology

• Here is someone using braid group implementation to do basic knot things https://quantumtetrahedron.wordpress.com/tag/knot-theory/

• Here is someone who even did some thinking about how to organize it: https://github.com/amitjamadagni/Knots/wiki/Knot-theory-implementation

• Here is where braid groups were implemented: http://trac.sagemath.org/ticket/12339
