/*

Representation a pair of real-value, two dimensional SafeCoordinates, 
From now on, this structure will be referred as "SafeCoordinate".

    This class represents a two-dimensional SafeCoordinate. Its main purpose is to
    serve as a normalized conversion format for data going in and out of the
    scripts contained in the project.

    Parameters:
    -----------
    - x: float
        The x-SafeCoordinate.
    - y: float
        The y-SafeCoordinate.


        The use of this structure will be inmutable, so every operation over 
        a SafeCoordinate will bring a new SafeCoordinate, unless the unsafe version 
        of each operation, this will be done to let the user choose between different
        options and use the one seems the best for him.
