Private Attributes
std::vector< std::vector< const dealii::DoFHandler< dim > * > >	dof_handlers
	Collection of the triangulation DoFs. The number of DoFHandlers should be equal to or less than the number of fields. Technically, there's a small optimization we can use when multiple fields have the same constraints and quadrature rule, allowing us to share the same DoFHandler. An example of this might be grain growth. Outer vector is indexed by field index. Inner vector is indexed by relative mg level.
std::vector< std::array< dealii::DoFHandler< dim >, 2 > >	level_dof_handlers
	A scalar and a vector dof handler for each level.
