public interface Vertex extends Element, Host
Vertex maintains pointers to both a set of incoming and outgoing Edge objects. The outgoing edges
 are those edges for  which the Vertex is the tail. The incoming edges are those edges for which the
 Vertex is the head.
 
 Diagrammatically:
 ---inEdges---> vertex ---outEdges--->.

VertexProperty for the provided key. If the property does not exist, return
 VertexProperty.empty(). If there are more than one vertex properties for the provided
 key, then throw Vertex.Exceptions.multiplePropertiesExistForProvidedKey(java.lang.String).default <V> VertexProperty<V> property(String key, V value)
VertexProperty.Cardinality.single.default <V> VertexProperty<V> property(String key, V value, Object... keyValues)
VertexProperty.Cardinality for that key.
 The default cardinality can be vendor defined and is usually tied to the graph schema.
 The default implementation of this method determines the cardinality
 graph().features().vertex().getCardinality(key). The provided key/values are the properties of the
 newly created VertexProperty. These key/values must be provided in an even number where the odd
 numbered arguments are String.V - the type of the value of the vertex propertykey - the key of the vertex propertyvalue - The value of the vertex propertykeyValues - the key/value pairs to turn into vertex property properties<V> VertexProperty<V> property(VertexProperty.Cardinality cardinality, String key, V value, Object... keyValues)
VertexProperty.Cardinality.single, then set the key
 to the value. If the cardinality is VertexProperty.Cardinality.list, then add a new value to the key.
 If the cardinality is VertexProperty.Cardinality.set, then only add a new value if that value doesn't
 already exist for the key. If the value already exists for the key, add the provided key value vertex property
