This is a package to rework the Lie group features of Manifolds.jl in a unified way into a separate package.

This especially also includes a few different choices in default behabiour that is different from the Manifolds.jl one. For purely manifold-based operations, any Lie group still is “build upon” a Riemannian manifold.

See #5 for an overview of fatures that are plannned. Feel free to add to this list with opening further issues.
