Title: Stochastic Gradient Descent for Linear SVM Training Added

Hi,

Kee Siong and I added the Stochastic Gradient Descent method for Linear SVM Training to online_sv.c. New functions are declared in online_sv.sql_in with their corresponding python wrappers in online_sv.py_in. Unit tests for the new functions are added to the kernel_mach.sql_in file. The usage documentation in online_sv.sql_in is already updated to incorporate the changes.

A bug in SparseData.c is also fixed.

I would appreciate if you could review the changes.

Thanks,
Jin
