Make it see if theres a template bridgedata

Add a check to see if template bridge data exists, and if it does, it will say please set variables and rename

There's some dev environment setup that I was missing, too, that you should apply in order to ensure your commits are good to go.

pip install pre-commit
pre-commit install

Then, when you commit, your code will get reformatted and checked for common Python errors.
