[name]
		
			A doubly linked list of vertices.
		
		Constructor
		[name]()
		
		
		Properties
		[property:VertexNode head]
		
			Reference to the first vertex of the linked list. Default is null.
		
		[property:VertexNode tail]
		
			Reference to the last vertex of the linked list. Default is null.
		
		Methods
		[method:VertexNode first]()
		Returns the head reference.
		[method:VertexNode last]()
		Returns the tail reference.
		[method:VertexList clear]()
		Clears the linked list.
		[method:VertexList insertBefore]( [param:Vertex target], [param:Vertex vertex] )
		
		[page:Vertex target] - The target vertex. It's assumed that this vertex belongs to the linked list.
		[page:Vertex vertex] - The vertex to insert.
		
		Inserts a vertex before a target vertex.
		[method:VertexList insertAfter]( [param:Vertex target], [param:Vertex vertex] )
		[page:Vertex target] - The target vertex. It's assumed that this vertex belongs to the linked list.
		[page:Vertex vertex] - The vertex to insert.
		Inserts a vertex after a target vertex.
		[method:VertexList append]( [param:Vertex vertex] )
		[page:Vertex vertex] - The vertex to append.
		Appends a vertex to the end of the linked list.
		[method:VertexList appendChain]( [param:Vertex vertex] )
		[page:Vertex vertex] - The head vertex of a chain of vertices.
		Appends a chain of vertices where the given vertex is the head.
		[method:VertexList remove]( [param:Vertex vertex] )
		[page:Vertex vertex] - The vertex to remove.
		Removes a vertex from the linked list.
		[method:VertexList removeSubList]( [param:Vertex a], [param:Vertex b] )
		[page:Vertex a] - The head of the sublist.
		[page:Vertex b] - The tail of the sublist.
		Removes a sublist of vertices from the linked list.
		[method:Boolean isEmpty]()
		Returns true if the linked list is empty.
