ENH added logging functionality to one-slack ssvm.
ENH add logger to subgradient ssvm
ENH add logger to n-slack ssvm
refactor: w is not always an attribute in learners
ENH repr for SaveLogger
make subgradient and cutting plane objectives comparable
keep track of real primal objective in one-slack ssvm
added link for utils.so
Add example to illustrate different optimization procedures
Flip sign of cutting plane ssvm for consistency
ENH in one-slack ssvm, refactor pruning, always compute primal objective
enh make constraint pruning in 1-slack ssvm slightly more intiutive
misc simplify
enh working on pruning constraints in n-slack
ENH compute final primal objective in one-slack ssvm
refactor subgradient_ssvm, add batches for n_jobs=1, massive speedups!
Add class weights to crammer-singer svm
