    /// 1) Create a new gameobject in the scene and attach this script on it
    /// 2) Create a prefab for the front and back pages(should be similar to the the page object that is created by the editor and has the same components)
    /// 3) Assign the front and back prefabs to this component
    /// 4) Call the function AddPaper when you want to add a new paper in the book
    /// 5) you may need to customize this function to add a paper in specific position in the book or to change some parts of the front and back prefabs dynamically
