The constructor is renamed from Ration  to Rational and exported.
(also add .gitignore)

1) Normalised 'over' when faced with negative denominators
2) Added various (mostly logical) combinators
3) Added some QuickCheck-style tests
4) Reverted to hiding the constructor to enable normalisation

  r *| i
  i |* r
  r |*| r

Also added more tests to investigate the behaviour of Rationals representing Infinity (Rational 1 0)

The idea is that the conventional comparison and arithmetic operands are used but whenever a Rational is at a given side of the operator, then the operator is 'protected' by a '|' character.  This both avoids clashes with Basics operators and also gives a method of predicting what the operator is with either one or two Rationals in a given context.

Also a naive implementation of the expected Expect.almostEqual function for comparing Floats in QuickCheck style tests.

This is a rough prototype of a possible future function for testing near-quality in numbers (particularly floats).
