Unit test fail in test_swath for test_self_map and test_self_map_multi

[cdeil]

I see two unit test fails from pyresample on Mac OS X 10.10 with numpy 1.9.1:

• Python 2: https://gist.github.com/cdeil/f89d37a9314d518228a8
• Python 3: https://gist.github.com/cdeil/c0767a434fafbe7a04d0

I think the fail is the same, but for some reason only on Python the values are printed by nose!???

There's also a bunch of warnings that I guess should be caught in the library or tests if it's normal and expected behaviour.

Thanks for reporting this @cdiel !
Unfortunately we have no access to macos machines here, and travis-ci doesn't seem to be wanting to run on osx at the moment, so it's a bit hard to debug. Do you have a possibility patch this and send a pull request ? Thanks !

@davidh-ssec @cdeil Are the unittests working in MacOS now ?

@mraspaud Yes they should now with commits 6a035f3 and ac6132c.
