./python.exe -m timeit -s 'from fractions import Fraction' 'Fraction(3)`

  ./python.exe -m timeit -s 'from fractions import Fraction' 'Fraction(3, 2)'`
27.7 usec/loop -> 9.32 usec/loop

  ./python.exe -m timeit -s 'from fractions import Fraction; f = Fraction(3, 2)' 'Fraction(f)'

Mark Dickinson 5f8bd3729e Replace R=fractions.Fraction with F=fractions.Fraction in 
test_fractions.py.  This should have been part of the name
change from Rational to Fraction.

Mark Dickinson d058cd2cc8 Rename rational.Rational to fractions.Fraction, to avoid name clash 
with numbers.Rational.  See issue #1682 for related discussion.
