/** \page smarttagger_docu Smart Tagger
The smart tagger can be used to tag vertices/halfedges/edges/faces on the mesh. It provides
an O(1) reset function to untag all primitives at once.
Usage:
\code
SmartTaggerVT< MeshType > tagger(mesh);
// Reset tagged flag on all vertices
tagger.untag_all();
// Check if something is tagged
bool tag = tagger.is_tagged(vh);
// Set tagged:
tagger.set_tag(vh);
\endcode
For details see OpenMesh::SmartTaggerT
