support `alembic check` command

[peterkronenberg]

Is there a way to do the equivalent of alembic check with flask-alembic?

Not currently, I didn't realize there was a new command in Alembic. You're welcome to submit a PR that adds the command. I'd guess all the parts needed are already there, for example Alembic.heads() would match Alembic.current() if all upgrades were run. You'd have to look at how check is implemented.
