Travis currently builds only against the latest Numpy version.
We however support Numpy versions down to 1.5, so new code should also be tested against that.
Looks good to me. Test failures are those from gh-3330.
Probably good to merge this only after those failures are fixed, otherwise all PRs will start failing.
gh-3392, gh-3393 should hopefully be the last ones before merging this is ok...
almost, one more after that ....
MAINT: make travis build one target against Numpy 1.5
OK almost there, so let's merge this before we introduce new issues again ......
