GitLab

- Adds a parameter class
- Adds a potential ParameterValue interface(?)
- Adds some new utils
- THIS WILL FAIL ON CI, srry I need to go to bed, so I'm committing
  what I've got.

- From here:
  - Test cases need to be written for the new parameter class
  - Test cases need to be written for the two new utils
  - Test cases need to be written for the changes to content line
