Reading and wrtiting from input file:

* GameLoader Class
    For reading and writing to input and output files respectively.
    The class reads the Map dimensions and then store each row
    to an array list which is used later to separte each land.
    I store hero types in array list as well as heroMovement which
    are later processed to each hero.
    Then, passing all the above data GameInput class.
    
* GameInput Class
    Store all data collected form the input file so it can be easily
    getted in the main game whenever needed.

        I added all common features among heroes in this class
        and any additional features is added in each specific hero.

* Extended classes

    - Knight
    - Wizard
