First cut on raw MultiplyHessianAdd for HessianFactor and JacobianFactor. Unit test is passed in testGaussianFactorGraphUnordered (multiplyHessianAdd3). Note the interface currently needs the accumulated diminsions of key variables. See GaussianFactorGraph::multiplyHessianAdd(double alpha,const double* x, double* y).

Standardized and corrected error handling on the linear size - underconstrained and negative systems always throw IndeterminantLinearSystemException, and all assertions checking for infinite values are removed. Also, we were not properly checking the result of Eigen's Cholesky, so sometimes elimination continued with incorrect matrices despite being underconstrained when Cholesky failed but did not produce NaN's.
