32 * This node represents a node that assist the scan of the graph. It could be a
33 * limit/border node such as StartingNode or EndingNode, or it could be
34 * trajectory node that changes the normal behavior of a node; this last means,
35 * that the node does not contain information about a token, but it helps to
36 * factor several ways, or to limit the quantity of visits of a way. Also it
37 * helps to write the grammar in a easier way for the user.
