Non-reversible models with branch-specific rates in v4.1?

[Joshua Mayoral]

Hi Ben,

Any possibility of updating the user's guide with a brief tutorial on using non-reversible substitution models with branch-specific insertion-deletion rates in version 4.1? 

I'd like to give these latest features a shot, but not quite sure how to setup those models based on the version 4.0 documentation. Apologies if I've missed their description somewhere.

Regards,

Josh
