Changes in version 0.2 -----------------------------------------------------------------

* colourise also works in screen terminal

* equals expectation provides more information about failure

* expect_that has extra info argument to allow you to pass in any extra
  information you'd like included in the message - this is very helpful if
  you're using a loop to run tests

* is_equivalent_to: new expectation that tests for equality ignoring
  attributes

* library_if_available now works! (thanks to report and fix from Felix
  Andrews)

* specify larger width and join pieces back together whenever deparse used
  (thanks to report and fix from Felix Andrews)

* test_dir now looks for any files starting with test (not test- as before)
