property
How to specify a property from a traversal.
Synopsis
g.addV('vertexLabel')
  .[ property ('property\_key') ... ]
Description
The property() step is a sideEffect.
When a vertex is added from a traversal g using addV, properties can be added with property().
For a previously created vertex, properties can be added.
A previously created vertex label must be specified.
Property key-value pairs are specified.
Examples
Create a vertex with a vertex label person with the properties personId with value 17and name with value Jamie Oliver:
g.addV('person').
   property('personId', 17).
   property('name','Jamie Oliver').next()Add the properties gender with value M and nickname with value jimmy to a person vertex previously created:
g.V().has('person', 'name', 'Jamie Oliver').
   property('gender', 'M').
   property('nickname', 'jimmy')Add the property withSuppliedId with value 341f9950-997c-11e7-9579-7f50358d3f8d to a person vertex:
// user-supplied property ID
g.addV('person').
   property('withSuppliedId', 'propValue', T.id, UUID.fromString('341f9950-997c-11e7-9579-7f50358d3f8d'))
