The main function will also support the following key functionalities: Reading the book records from the textfile [0.5 pt]: The file text "books.txt", provided along with the assignment has lines with the following format: title:genre:author-1,author-2,...author-m:tag:no-of-pages Read each line, create BookRecord object for each book and insert in the Vector/ArrayList.
