bc-kotlin now using main as principal branch.

[dghgit]

Hi everyone,

We've just changed to using main as the principal branch - it's a simple rename. Instructions for updating locally below.

Regards,

David

Get the latest commits and branches from the remote:

$ git fetch

Make sure on master branch

$ git checkout master

Rename "master" to "main":

$ git branch -m master main

Remove the existing tracking connection with "origin/master":

$ git branch --unset-upstream

Create a new tracking connection with the new "origin/main" branch:

$ git branch -u origin/main
