 - Class "Aluno" can be used to instantiate objects of type Aluno.
   Each Aluno object will have a "Matricula", two grades ("Notas"),
   and also the final grade.

 - Class "Vetor" has two arrays. An array of "Aluno", and an array of bool.
   The array of bool will have true in the positions where there is
   a valid Aluno. The "empty" positions of the bool vector will have false.
   
 The two classes can be arranged in a class hierarchy as shown
 below. It is an "aggregation", where Class Vetor "has" Class Aluno.  
 In this relationship, the child can exist independently of the parent.

          +----------------+
          |     Vetor      |
          +----------------+
                 / \
                 \ /  has
                  |
                  |
          +----------------+
          |      Aluno     |
          +----------------+

 In the main program, a menu is used for the user to select which action will
 be performed in the vector.
