// The topoSetDict comprises a list of actions to perform on different
// set types (cellSet, faceSet, pointSet, etc).
//
// Each action is a dictionary with e.g.
// // Name of set
// name c0;
//
// // type: pointSet/faceSet/cellSet/faceZoneSet/cellZoneSet
// type cellSet;
//
// // action to perform on set. Two types:
// // - require no source : clear/invert/remove
// // clear : clears set or zone
// // invert : select all currently non-selected elements
// // remove : removes set or zone
// // - require source : new/add/subtract/subset
// // new : create new set or zone from source
// // add : add source to contents
// // subtract : subtract source from contents
// // subset : keeps elements both in contents and source
// action new;
//
// The source entry varies according to the type of set.
//
// In OpenFOAM 1806 and earlier, it was compulsory to use a 'sourceInfo'
// sub-dictionary to define the sources.
// In OpenFOAM 1812 and later, this sub-directory is optional, unless
// there would be a name clash (Eg, 'type' or 'name' appearing at both levels).
// In most cases, the source definitions have been adjusted to avoid such
// clashes.
