Don't kill whole test chain with sys.exit
drop libstdc++ workaround from cmake lists

for osx we need swig 3.0.0 (currently git clone only) for a modular
interface to work
use expect_near macros when comparing results
seed rng to get reproducible tests
fix compile error occurring with swig3
Fix libc++ and libstdc++ mixup on OSX with swig 2.0.11 or earlier
mute warning about serialization version
make canned data tests python version specific
Lower precision for SGVectorTest.dot
fix generator for python3 and add python3 integration test data
Fix python3 tests

- use uncompressed data in mathematics* to workaround an error in python3.2
- do not test dynprog on python 3 (it requires pickled numpy data...)
- histogram kernel creates huge values when using order > 1 that are
lossy represented as ascii creating test failures. Use order = 1 for
tests
- fix tester for python3 and its debug mode
- fix typos in parameter/datatype and print out proper info messages
when results differ
require new data version
require new data
decrease accuracy to 1e-14
enable tests previously failing on travis
drop the cPickle import that might kill python3 serialization tests
use higher precision (eps 1e-7) for example
require new data version w/ python3 regression tests
add mathematics_logdet.py to blacklist
disable svmlight batch example for now
