    #n can be an Integer or a Range.  If it is an Integer, it just returns a random
    #number greater than or equal to 0 and less than n.  If it is a Range, it
    #returns a random number within the range
    # Examples
    #
    # >> Random.number(5)
    # => 4
    # >> Random.number(5)
    # => 2
    # >> Random.number(5)
    # => 1
