Our implementation is using synonymous names for parameters compared to the paper by J.A. Wollmershauser, B. Clausen, and S.R. Agnew.
'xi_inf' and 'chi_inf' are not strictly "asymptotic values", but stresses that correspond to the back-extrapolation from the terminal linear hardening stage (characterized by 'h_inf_xi/chi').
All parameters are referenced back to their counterparts in the paper by J.A. Wollmershauser, B. Clausen, and S.R. Agnew.

we don't use random numbers a lot and there are no reported problems
yet.
Still, this is safer.

Re-written YAML types
...
Strict typing for YAML
New access pattern requires to specify the expected type, i.e. 'scalar', 'list', or 'dict'. This ensures that the node offers the expected functionality instead of polluting 'tNode' with dummy functions which throw error messages if not overwritten.
The restructuring of the code allows to hierarchically construct methods without much code duplication.
Some aspects of the error messaging system have been improved.
