Refactored the svm_nu_trainer. Specifically, I pulled the quadratic · b7a02418

solver out and made it a separate class.  The kernel_matrix_cache has also
been removed in favor of the new symmetric_matrix_cache.  Finally, the
remaining bits of the svm_nu_trainer have been moved into svm_nu_trainer.h

Also note that invalid_svm_nu_error has been renamed to invalid_nu_error.
