While this may be worth revisiting, we should first quantify the benefits and identify the compilers that support it. Ultimately, we may never use pragma once in favor of strictly using standard C++.

// Class supporting "selection" of components in a Level for sparse Refinement.
|
|
// The term "selection" here implies interest in the limit for that component, i.e.
|
|
// the limit point for a selected vertex, the limit patch for a face, etc. So this
|
|
// class is responsible for ensuring that all neighboring components required to
|
|
// support the limit of those selected are included in the refinement.
|
|
//
|
|
// This class is associated with (and constructed given) a Refinement and its role
|
|
// is to initialize that Refinement instance for eventual sparse refinement. So it
|
|
// is a friend of and expected to modify the Refinement as part of the selection.
|
|
// Given its simplicity and scope it may be worth nesting it in Vtr::Refinement.
|
|
//
|
|
// While all three component types -- vertices, edges and faces -- can be selected,
|
|
// only selection of faces is currently used and actively supported as part of the
|
|
// feature-adaptive refinement.
