Implement Model finder with Tabor parameter

[paulmueller]

When the maximum adhesive (pull-off) force F ad is large enough in
comparison with the maximum force F max applied during load-
ing, i.e. for |F ad /F max |> 0.05 [28], which is frequently observed
in retraction curves, Hertzian analysis is no longer valid and
models for adhesive contact of spheres should be invoked. These models
include the JKR (Johnson–Kendall–Roberts), DMT
(Derjaguin–Muller–Toporov), and Maugis models

The dimensionless Tabor parameter � = (R� 2 /E 2 � 3 ) 1/3 is
used to choose the suitable model [31]
