Function to set and get which edition of default choices is being used.
Details
The mizer functions for creating new models make a lot of choices for default values for parameters that are not provided by the user. Sometimes we find better ways to choose the defaults and update mizer accordingly. When we do this, we will increase the edition number.
If you call defaults_edition() without an argument it returns the
currently active edition. Otherwise it sets the active edition to the
given value.
Users who want their existing code for creating models not to change behaviour when run with future versions of mizer should explicitly set the desired defaults edition at the top of their code.
The most recent edition is edition 2. It will become the default in the next release. The current default is edition 1. The following defaults are changed in edition 2:
catchability = 0.3 instead of 1
initial effort = 1 instead of 0
