7    o pkg/seaice/seaice_evp.F: introduce "adaptive EVP" by Madlen Kimmritz
8      - this is an intermediate state of a truely converging EVP that has
9        the potential of outperforming implicit VP methods, I do not recommend
10        using it yet.
11      - for now, "adaptive EVP" is turned on by setting SEAICE_EVP_USE_ADAPTATION
12        and all parameters are hardwired
13      - for convergence it still requires very smooth regularisations, that means,
14        if SEAICE_DELTA_SMOOTHREG is defined, deltaCreg=deltaC+deltaMin, which is
15        different from the VP case with deltaCreg=sqrt(deltaC**2+deltaMin**2); also
16        specific averaging appears to be required, still subject to tuning
17      - still needs cleaning and I need to turn parameter into runtime parameters
18      - add code to compute and print residuals of iteration, compile with
19        defining ALLOW_SEAICE_EVP_RESIDUAL to enable it
