Wrong bracket around sine?
PEP 8 and more idiomatic code in image/tests/test_resample.py

Use spaces instead of tabs and also use ``is None`` or ``is not None``
instead of ``== None`` or ``!= None``, respectively.

[BugFix]: PEP 8 and more idiomatic code in image/tests/test_resample.py
renamed chaincode_test.py to test_chaincode.py

This is required so that py.test detects this file automatically as a
test file and execute its test functions.

MRG: Wrong bracket around sine?
Add changelog entry for PR #961
Set date kwarg explicitly when calling goes_chianti_tem() in test_tem_em()
instead of using DATE-OBS in GOESLightCurve object meta data to
make the test more robust.
Tidied up line lengths in get_goes_event_list().
Added import of division from __future__
Clarified which functions are public and non-public in goes.py.
Put public functions in __all__ list at top of script and added
leading _ to names of non-public functions.
Also deleted Extended Summary titles from docstrings.
Replaced usage of check_goeslc in temp_em() with simpler code.
Replaces use of check_goessat() in goes.py with simpler lines of code.
Replaced usage of check_date in goes.py with simpler lines of code.
Replaced usage of check_float() in goes.py with simpler lines of code.
Changed kwarg photospheric in all relevant functions in goes.py
to abundances equal to "coronal" or "photospheric" instead of a
True or False boolean in order for code to be clearer.
Created function, _set_abundances() in goes.py to check input
value of abundance kwarg and also create a file name suffix
for accessing the correct csv file depending on abundance.
Replaced all usage of check_photospheric() with
_set_abundances().
Fixed bug in _set_abundances().  Return statement was missing.
Extended test_goes_chianti_tem() to check all possible cases.
Tidied up temp_em().
Changed ValueError to TypeError in checking GOESLightCurve input to temp_em().
