BooleanComboMarker

Description

The BooleanComboMarker class combines multiple other markers together using boolean operations. The markers provided in refine_markers are responsible for determining if an element should be refined, while the markers provided in coarsen_markers are responsible for determining if an element should be coarsened. Setting boolean_operator to and will require all refine_markers to return MarkerValue::REFINE before BooleanComboMarker marks an element for refinement. Setting`boolean_operator` to or will require a single marker to return MarkerValue::REFINE before an element is marked for refinement. The same holds true for coarsen_markers with MarkerValue::COARSEN. In the event both the refinement and coarsening expressions are true, the preferred refinement operation (priority) is used to determine if the element is marked for refinement or coarsening.
