If `f : ℂ → F` is complex-differentiable, then show that `f` is harmonic. If `F = ℂ`, then so is its real part, imaginary part, and complex conjugate. If `f` has no zero, then `log ‖f‖` is harmonic.

This material is used in [Project VD](https://github.com/kebekus/ProjectVD), which aims to formalize Value Distribution Theory for meromorphic functions on the complex plane. It is one of the ingredients in the proof of Jensen's Formula in complex analysis.
