Adding ard_regression()

[ddsjoberg]

What changes are proposed in this pull request?

• Migrated ard_regression() from {cards} and made it an S3 method. I think different types of models classes will need different handling, which is why S3 is a good option here.

Looks great! Just a few suggestions to link the mentioned functions within the documentation. Then it should be good to go :)
