…phy, with tests: INCOMPLETE WIP

…test

* Put orca_util routines in subpackage of iris.test.stock, to get existing iris.tests.unit.plot.test_2d_coords working.

* Disable broken misused testcode in test_gridcell_angles.

* Ditch test_gridcell_angles, none of it is functional.

* Further style fixes.

* Skip tests using iris-test-data, for Travis TEST_MINIMAL phases.

* Codestyle fix (though this code obsolete anyway).

* Fix unused imports.

* Made-up test cube replaces use of iris-test-data.

* Renamed keyword; improved docstring.

* Change 'co' to 'coord' for clarity.

* Review changes.

* Small improvements; first sensible tests.

* Enhanced testing; better checking and crs awareness in grid_angles routine.

* Remove crud from test_gridcell_angles.

* Use degree units for everything in _grid_angles.

* Make assertArrayAllClose print details when it fails.

* Rework and extend testing for gridcell_angles.

* Fix assertArrayAllClose; remove debug code from test_gridcell_angles.

* Remove obsolete assignments.

* Remove obsolete code.

* Small comment improvements.

* Attempt to clarify docstrings of low-level routines.

* More tests, and some functional fixes.

* Codestyle fixes.

* Review changes + fixes.

* Avoid using sample data.

* Tests for rotate_grid_vectors.

* Small fix to assertArrayAllClose for values near 0.

* Small tweaks.

* Fix test method.

* Fix 1 test for 'equal_nans' no longer the default.

* Review changes.

…s#3149)

Attempt to fix Matplotlib issue by resticting to 2.x

* Realise that running the tests is simpler than I thought

* Make Gracefully warning only appear when filling is required

* Add tests of warnings

* Get rid of install changes, they are in SciTools#3170

* Update after review

* Add whatsnew entry

* turn columns object into pandas array, plus test

included cml this time

* made things the way pandas like it; bambooish

* regenerated cml to match output

* Update module headers and installation instructions

* Realise that running the tests is simpler than I thought

* Update install instructions for developers

* Update INSTALL to be consistent

Added one line on how to test. This is mentioned in the Iris Check List in pulls.rst list, but would be good to have it here as well (useful for new contributors like me).

2d coords

minor requirements tidy

* Handle printing time bounds

* Whatsnew, whitespace fix for test result

* make cube reversing official

* review: test conventions, etc.

* review: enable coord specification

* add whatsnew

* review: AssertRaises --> AssertRaisesRegexp

* cube error handling

SciTools#3182)

* Tests for expected behaviour

* Raise error if aux factory relies on a coordinate external to cube

* Include coordinate name in error message

* Don't check whether dependencies that are "None" are in the coords.

* Review changes: check cube name in error and variable rename

* Truncated variable for flake8
