contains(const std::complex<T>& v): Determines whether the given $v ∈C$ is in the current interval $X ∈ RC$ , that is $v∈ X$ .
contains(const kc_interval<T>& o): Determines whether the given $O ∈ RC$ is contained in the current interval $X∈ RC$ , that is $O ∈X$ .
overlaps(const kc_interval<T>& o): Determines whether the given $O∈ RC$ overlaps with the current interval $X ∈RC$ , that is $∃v∈ R$ such that $v∈ X∧ v∈ O$ .
