CirclePath(r::Real)

Define a circular path of radius `r` centered around the origin.

isclosed(γ::AbstractPath)::Bool

Check if `γ` is a closed Path. i.e. the start and end points are the same (within a tolerance because of floating point math).

pointsonpath(P::Path, n::Integer)

Return a vector of `n` evenly spaced points along path `P`.
