Add isconstantfun and check while converting to ConstantSpace #632

Closed jishnub closed 5 months ago

jishnub commented 5 months ago

After this, coefficients for non-constant Funs can't be evaluated in a ConstantSpace. The following works on master, but will be disallowed:

julia> coefficients(Fun(Chebyshev(0..1)), ConstantSpace(0..1))
2-element Vector{Float64}:
  0.5
 Inf

The newly added function isconstantfun is intended to be extended by downstream packages to provide more efficient implementations.
