    @class      MPFractionFunction
    @abstract   This class represents a fraction.
 
    @discussion A fraction has two children: the nominator and the denominator.
                Typically it is displayed with a horizontal bar between the two
                child expressions which are on top and below the bar
                respectively. When a fraction is evaluated the nominator is
                divided by the denominator.
