Clean property based testing for python

========================================

Example usage: sqrt.py::

  from quickconstraint import constrain

  @constrain

  def sqrt(x2: lambda x: 0 <= x):

      x = 1

      while not approx(x*x - x2):

          x = (x + x2/x)/2.0

      return x

test-sqrt.py::

  from quickconstraint import theorem, test_all_theorems

  @theorem

  def theorem_sqrt_sq_inverse(n): return sq(sqrt(n)) == n

  if __name__=="__main__":

      test_all_theorems()
