TODO: Write a class that represents a Food item:

present when created...(set to 100 if not present - default value)
 + Has one accessor function (getCalories) and one mutator function (you decide what to mutate)
 + All attributes must be private
 + When you print an instantiated object of this Food class, it must be in the form:
"FoodName (# calories)"
