graph-matrix-vertex	Stub for matrix based graph. Not implemented.

Slot

color	The `color` is used by some algorithms for bookkeeping. [?? Should probably be in a mixin] Initargs::color; Accessors:color.
depth-level	`Depth-level` is used by some algorithms for bookkeeping. [?? Should be in a mixin] Initform:0, Initargs::depth-level; Accessors:depth-level; Type:number.
discovery-time	`Discovery-time` is used by some algorithms for bookkeeping. [?? Should be in a mixin] Initform:-1, Initargs::discovery-time; Accessors:discovery-time.
element	Initargs::element,:value; Accessors:element, value.
finish-time	`Finish-time` is used by some algorithms for bookkeeping. [?? Should be in a mixin] Initform:-1, Initargs::finish-time; Accessors:finish-time.
graph	The `graph` of which this edge is a part. Initargs::graph; Reader:graph.
next-node	`Next-node` is used by some algorithms for bookkeeping. [?? Should be in a mixin] Initargs::next-node; Accessors:next-node.
previous-node	`Previous-node` is used by some algorithms for bookkeeping. [?? Should be in a mixin] Initargs::previous-node; Accessors:previous-node.
rank	The `rank` is used by some algorithms for bookkeeping. [?? Should be in a mixin] Initargs::rank; Accessors:rank.
tag	The `tag` is used by some algorithms for bookkeeping. [?? Should probably be in a mixin] Initargs::tag; Accessors:tag.
vertex-id	`Vertex-id` is used internally to keep track of vertexes. Initform:0, Initargs::vertex-id; Reader:vertex-id.
