Walkthrough

Ohayo, sensei! The recent updates enhance the dojo-core library by adding the public function selector_from_names in the utils module, allowing the computation of resource selectors. Additionally, a new test function, test_selector_computation, has been introduced to validate this functionality within the test suite. These changes aim to improve both the utility and robustness of the library.
