-- Added ability to specify non-zero Dirichlet boundary condition
-- Updated transient conduction example to include a non-zero boundary condition on the left boundary
-- Added a call to DofMap::enforce_constraints_exactly() for System::solution in NonlinearSystem::solve(), since libMesh::NonlinearImplicitSystem::solve() only calls this method on System::currentl_local_solution
