Best use case and examples for functions in complex plane

[heltonmc]

Thank you for this package! It has been very helpful over at Bessels.jl

Is the best way to use this package to approximate functions in the complex plane is by setting it up as a 2D problem?

g(x) = sin(x[1] + im*x[2])
lb, ub = [1,3], [2,4]
x = chebpoints((10, 20), lb, ub)
c = chebinterp(g.(x), lb, ub)

julia> g([1.2, 3.4])
13.979408806017995 + 5.422815472463402im

julia> c([1.2, 3.4])
13.979408806018007 + 5.422815472463357im

Or is there a better more recommended approach to do this ?
