fix serialization, it now works on bikes

    add writeFile() so when the constuctor is destroyed, it writes all
    add getElems()
update main, substitute libel, add the right bikes.txt

    main method does nothing, it just creates a Controller<Bike> and
    destroys it, if bikes.txt is inchanged and nothing crashes after
    multiple execution, then it works...
add get&set for Libel and add comments
format header macro gates to be consistent w/ dev chart
remove silly object files
add gitignore
update Bikes and make a pretty main fct

    add attributes to Bike w/ getters & setters
    update constructor and serialization to fit w/ the new stuff
    add comments to Bike.cpp functions
add comments to Controller h and cpp fcts
add comments to Serializable functions

    and add "inherited from Serializable" in Bike's serialization methods
update author in header comments
add Station and Emplacement model class
add tests and instanciate Controller for new classes
remove unnecessary include
