    For use on books that use "Chapter #" as their chapter format. 
    
    * The first parameter is the title of the book's page.
    
    * The second parameter is the number of chapters in the book (not counting the prologue, epilogue, or any other bonus chapters)
    
    * The third parameter is optional, and should be "true" (case insensitive) if there is a prologue for the book. Any other value will be interpretted as "false".
    
    * The fourth parameter is optional, and should be "true" (case insensitive) if there is a prologue for the book. Any other value will be interpretted as "false".
    
    * The fifth parameter is optional, and is for an additional chapter at the end of the book that doesn't follow the standard naming conventions (e.g. post-epilogue). The value should be the title of the chapter.
