Changing default branch from master to main

[John Wise]

Hi all,

In this week's Enzo-E workshop, there were no objections to change the
branch name from master to main for both Enzo and Enzo-E. Many codes
are doing this, and github makes it relatively painless to make the
change. See this site for more details

https://github.com/github/renaming

Users with forks will receive a message that the default branch has been
renamed with instructions on how to update their local copies.

I will make this change shortly after this email. If anyone runs into
any issues, please let us know.

Thanks,
John
