Tests/improving linear tests

[aqitya]

Improved Linear Tests by making testing more robust via setter and getter methods and providing greater range of testing for given parameters.

Implemented eq for linear models.

Added a copy and serialize functions in linear tests that are not complete, but is included because it is code that will be used but later revamped.

Furthermore, created a eq function in parameters.py that is being tested in test_base_models. The tests need to test other types of datatypes.

Moved composite model tests to test_composite.py file. (No changes were made to the tests)

Thank you for opening this PR. Each PR into dev requires a code review. For the code review, look at the following:

• [ ] Reviewer should look for bugs, efficiency, readability, testing, and coverage in examples (if relevant).
• [ ] Ensure that each PR adding a new feature should include a test verifying that feature.
• [ ] All tests must be passing.
• [ ] All errors from static analysis must be resolved.
• [ ] Review the test coverage reports (if there is a change) - will be added as comment on PR if there is a change
• [ ] Review the software benchmarking results (if there is a change) - will be added as comment on PR
• [ ] Any added dependencies are included in requirements.txt, setup.py, and dev_guide.rst (this document)
• [ ] All warnings from static analysis must be reviewed and resolved - if deemed appropriate.

I jsut ran all the tests once more, they all passed (other than the benchmarking one), but I am rerunning without some additional files that were cluttering the repo (the previous test.txt file that Chris told me to remove)

All the changes from dev have just been moved onto this branch^
