I've implemented the ShareBoost algorithm. The libshogun example works fine in my local box. Please review and merge this.

Next I'll try to modify the integrated liblbfgs to make it more C++ and more Shogun.

And here comes the refactoring of lbfgs:

  • use SGVector operations instead of those provided in lbfgs
  • use shogun memory management operations
  • wrap the code in shogun namespace
