Detailed Description

Class for Matrices with few rows that consists of Vectors, together with a premultiplied Expansion matrix.

So, the matrix is V^T*P^T. If P is NULL, it is assumed to be the identity matrix. If a row vector of V is NULL, it is assumed to be all zero. This is used to construct the KKT system with low-rank Hessian approximation.
