PR Summary

• Introduction of Codecov Configuration File
  A new file named codecov.yml has been added. This is a configuration file for Codecov, a tool used to measure the extent to which the codebase is covered by tests. This helps improve the quality of the code by ensuring that more of it is properly tested. The configuration file is specifically set to ignore the directories 'demo' and 'docs', meaning any code within these will not be included in the Codecov reports. This will help focus results on the core parts of our application and not on the example or documentation code.
