while I was at it I removed this test because it tested pca_comps which is now deprecated. It failed (when it passed before) probably because of the random_seed, which may change because of this PR

I set the random seed here to pass the test, because the random_seed may be different than before.

LGTM. There is just some conflicts with master to address before we can merge |

There was a small pb with the merge but it should be fixed right now, if it's green I think we can merge |

It's probably safe to remove this check, as all callers of _pairs should have done it already.

Fixes #171
This PR replaces the
random_seedinfit, by therandom_seedininit.Note that I also updated the functions
positive_negative_pairs,_pairs, andadjacency_matrixto be more like scikit-learn (i.e. have a therandom_stateparameter to beNoneby default), but I don't think it's necessary to put aChangedBehaviourWarning or aDeprecationWarning, since those are util functions, that were not previously documented, (and probably less used than*_Supervisedversions of algorithms), and what is more the previous behaviour will still work (givingnp.randomor anyRandomState), what do you think ?
