Issue:
Neg tri tidy up
## Proposed changes

Makes some pep changes using flake8 to the code

## Types of changes

What types of changes does your code introduce to the Paramak?

- [ ] Bugfix (non-breaking change which fixes an issue)
- [ ] New feature (non-breaking change which adds functionality)
- [ ] Breaking change (fix or feature that would cause existing functionality to not work as expected)
- [x] Code refactoring
- [ ] Documentation Update (if none of the other choices apply)
- [ ] New tests

## Checklist

- [ ] I have added tests that prove my fix is effective or that my feature works
- [ ] I have added necessary documentation (if appropriate)

-This folder contains a development version of Paramak that is used for testing.

-One of the differences between this conda build and the main conda build is that
-this version makes use of CaDQuery master instead of a stable version of
