Adaption of Fresnel-Tikhonov phase retrieval algorithm to re-implemented BacktrackingPGM.
Change solver algorithm to re-implemented BacktrackingPGM.
Also
- add nonlinearity low-frequency correction term for CTF warm-starts
- change minimal iterations of CTF warm starting to at least 100
- CTF step size is not adjusted with Tikhonov step size any more.
- Add simple functional operator algebra.
Note: the signature for Tikhonov
slightly changed for keyword options.
