NAME

       Graph::MoreUtils::Line::SelfLoopVertex - marker for artificial self-loops

DESCRIPTION

       With "loop_end_vertices" option Graph::Line adds self-loops on pendant vertices thus
       preserving them from getting "lost".  Instances of Graph::MoreUtils::Line::SelfLoopVertex
       are used to represent the artificial self-loops in the resulting line graphs.
