Abstract PETSc object that manages treating several distinct vectors as if they were one. The <A HREF="../DA/VecPack.html#VecPack">VecPack</A> routines allow one to manage a nonlinear solver that works on a vector that consists of several distinct parts. This is mostly used for LNKS solvers, that is design optimization problems that are written as a nonlinear system
