public void setVertexType(String vertexType) {
		setAttribute(VERTEX_TYPE_KEY, vertexType);
	}
Sets the vertex type for this vertex. Should be a value defined by the {@link GraphType} for
this graph, but there is no enforcement for this. If the value is not defined in GraphType,
it will be rendered using the default vertex shape and color for the {@link GraphType}
@param vertexType the vertex type for this vertex
