Github release of code for computing with Heisenberg and Clifford groups built on arbitrary abelian groups (T3.1)

Stable release of open source Julia code for computing representations, cohomology, group algebras and other algebraic invariants of Heisenberg and Clifford groups over algebraic number fields using OSCAR (Open Source Computer Algebra Research system). This will enable exact computations in small dimensions that will further inform our theoretical investigations into the arithmetic structures of their orbits on states, codes, circuits, polytopes, etc. It will also let us study the role played by non-isomorphic maximal orders in questions of exact circuit synthesis in arithmetic groups.
