2) SolverMaster hided from user
3) Examples fixed with new Solver Class

Cleanup of Row class and Matrix class.

Significantly reduced memory required for Row class and consequently for
multivar_expression class. Moved out openmp locks and row annotation as
additional service classes.

Introduced classes HessianRow and HessianMatrix for future possibility
of hessian computation in automatic differentiation.
