description:
Clean up of nonlinear solver.

NonlinearFunction is now a simple base class, for which a user provides functions to compute a RHS vector and the Jacobian matrix.

What was NonlinearFunction is now largely NonlinearPDE, which is not dissimilar to the class PDE. Given a BilinearForm, LinearForm, Mesh, and BoundaryCondition, it will form the residual vector and the Jacobian, or this can be provided by the user by deriving a class from NonlinearPDE.

NewtonSolver now uses the new parameters system. Defaults are set in the constructor and have been removed from DefaultParameters.h.

description:
Allow local data to be attached to Functions:

  void attach(Vector& x,              bool local = false);
  void attach(Mesh& mesh,             bool local = false);
  void attach(FiniteElement& element, bool local = false);

If local is set, the data will be considered local to the Function.
The Function takes responsibility for the data (including deletion at
the appropriate time). Use with caution.

This is mainly to be used when reading Function data from file, when we
need to create the Vector, the Mesh and the FiniteElement (they are not
references to somebody else's data).
