Fetching a reference field value from higher-level parents when there is a field containing the parent record in the children and the use-case reference field is present in all tables

In this before insert or update Business Rule, we are fetching a reference field value from higher-level parents in hierarchy when there is a field containing the parent record in the children and our use-case reference field is present in all the tables in hierarchy

@Soumyadeep10 thanks for your contribution. However, there are few suggestions. Please correct the name of readme.md file (it contains small 'm'). Make sure that readme.md describes your snippet clearly. PR name can be more brief. Please correct these things and and recommit them.
Edit: One more thing, please restructure the files. You need to have a subfolder of your snippet in main folder for e.g. Business Rules/your snippet folder name/script.js (same goes with read,me.md file). Closing this for now, feel free to reopen the same PR or create a new one once the changes have been made.
