Correct the Unify Function Implementation

[TeamSPoon]

The current implementation of the unify function is not behaving as intended and needs to be corrected. Specifically, the unify function should behave more like a match function, ensuring that the first two arguments are not incorrectly unified.

Task

1. Rewrite the unify Function:

   • Modify the unify function to behave more like a match function rather than incorrectly unifying the first two arguments.
   • Ensure the logic properly reflects the intended behavior for matching rather than unification.

2. Verify Correctness:

   • Test the rewritten function thoroughly to ensure it behaves as expected in various scenarios.
   • Ensure that the first two arguments are not being incorrectly unified.

3. Document the Changes:

   • Update any relevant documentation or comments in the code to reflect the changes made to the unify function.
   • Include examples or test cases in the documentation to demonstrate the correct behavior of the function.

Acceptance Criteria

• The unify function is correctly rewritten to behave as a match function.
• The first two arguments are handled correctly, without incorrect unification.
• The function passes all relevant test cases.
• Documentation is updated to reflect the changes.
