move old stuff to the attic, rename lp_new to linear_programming
more flexible toy datasets
test kmeans initialization
ENH less hacky solution to checking if the slacks work out.
Allow symmetric edges in kmeans initialization
fix typo in crosses, more flexible generation
remove unused import
TST test latent svm, allow custom initialization
dont' always dump images in structured svm
Minor cleanup in LatentGridCRF
Added LatentDirectionalGridCRF
FIX latent svm didn't respect the choice of inference method... d'oh... also mess with 32bit integer overflows...
examples with directional CRFS
FIX LatentDirectionalCRF initialization
New bars dataset
docstring blub
bars have two classes
Test LatentDirectionalGridCRF
arbitrary graphs for ad3, again a little more precision for qpbo
test all inference methods where possible
