class Team():
    """
    A team of units.
    
    Very similar to the Teams class, but this one loads units, so it's not
    safe to have as property of Unit.

    Parameters
    ----------
    id : str
        Team identifier.
    name : str
        Team name.
    priority : int
        Team priority, from 1 to 50.
    units : Unit[]
