//  Purpose: This program allows the user to search the database for a
//           certain book title and view the book information for it (latter
//           occurs when bookinfo function is called).
//
//--------------------------------------------------------------------------
//  Algorithm:
//      Step 1: Display Menu Options to the console and prompt user to make
//              a selection.
//      Step 2: Take in search title
//      Step 3: Either retun titles that were found and allow the user to
//              view desired book info or prompt that no books were found.
