🚩Milestone 6: preserve data | read/write - >>branch<< -

Hi there! @NitBravoA92 and @ahmedeid6842 here. 👋

This is the PR for the preserve data activity. The main objective of this Milestone is to learn how to preserve the data from the application and load preserved data on startup.

Here is a summary of what has been done:

• Modify the Book class to add a new instance variable called id and the method to_json to convert the Book data into a hash.

• Modify the Rental class to add a new instance variable called id.

• Modify the Person, Student, and Teacher classes to receive an incremental id

• Modify the Student and Teacher classes to add the to_json method that converts the data into a hash.

• Create the DataRepository module that contains the following methods:
  -find_all_books: Read all the books' data from the books.json file
  -find_all_people: Read all the people's data from the people.json file
  -find_all_rentals: Read all the rentals' data from the rentals.json file
  -save_books: Write the books' data into the books.json file
  -save_people: Write the people's data into the books.json file
  -save_rentals: Write the rentals' data into the rentals.json file
  -get_data: This is a helper method that takes the name of a file with its extension, validates that the file exists, and extracts information from it.
  -insert_data: This is a helper function that receives the name of a file with its extension and the information to save, and writes or creates a file with that information.

• Include the DataRepository module in the App class.

• Modify the App class to get the books, people, and rental data from the JSON files when the app starts.

• Modify the App class to save the books, people, and rental data into the JSON files when the app finishes its execution.

• Update the menu method in the UserInterfaceActions class to call the finish method of the App class, which persists the data at the end of the application execution.

• Update the README.md file
