rename linear manifold to Euclidean?

[tiemvanderdeure]

I'm not a mathematician and a little out of my depth here, but the name Linear seems unintuitive to me for calculations in Euclidean space. Why don't we call it Euclidean? Linear sounds kind of 1D. If we want to specify that it is 2D space we could call it Planar, but I don't think that we do?

GeometryOps.jl/GeometryOpsCore/src/types.jl

Lines 38 to 45 in 737340f

	"""
	Linear()
	A linear manifold means that the space is completely Euclidean,
	and planar geometry suffices.
	"""
	struct Linear <: Manifold
	end

Manifolds.jl also calls their manifold in euclidean space Euclidean: https://juliamanifolds.github.io/Manifolds.jl/latest/manifolds/euclidean.html

I was also confused about what Linear meant, +1 for Euclidean

I would be fine with either Planar or Euclidean, but I feel like Planar is a bit more descriptive about what is actually going on?

[rafaqz]

I guess those methods will always be 2d?

[asinghvi17]

Most likely, if we go into 3d we can always soft-deprecate Planar for Euclidean
