svm doesn't work

[zrccxyb62]

Hi, thanks a lot for your great work. But I found something about the svm is not fully functional, and I debuged some of them, but it still doesn't work.

1. there misses a smo_csvc_train_test_by_sample.py
2. the smo_csvc_train_test.py has some bugs, the accuracy calculation part always reports float division by zero and other parts too. like:
   ( File "/root/tim/0.2/example/../pymining/classifier/smo_csvc.py", line 738, in Train
   self.b = ((b1/(c1))+(b2/(self.model.svn - c1)))/2
   ZeroDivisionError: float division by zero
   )
3. Some test files are missing.
