@brief The result of the query is the path to all elements.

`graph_query.path()`

By defaut the result of the generated AQL query is the set of elements passing the last matches.
So having a `vertices()` query as the last step the result will be set of vertices.
Using `path()` as the last action before requesting the result
will modify the result such that the path required to find the set vertices is returned.

@EXAMPLES

Request the iteratively explored path using vertices and edges:

@EXAMPLE_ARANGOSH_OUTPUT{generalGraphFluentAQLPathSimple}
  var examples = require("@arangodb/graph-examples/example-graph.js");
  var graph = examples.loadGraph("social");
  var query = graph._vertices({name: "Alice"});
  query.outEdges().toVertices().path().toArray();
~ examples.dropGraph("social");
@END_EXAMPLE_ARANGOSH_OUTPUT

When requesting neighbors the path to these neighbors is expanded:

@EXAMPLE_ARANGOSH_OUTPUT{generalGraphFluentAQLPathNeighbors}
  var examples = require("@arangodb/graph-examples/example-graph.js");
  var graph = examples.loadGraph("social");
  var query = graph._vertices({name: "Alice"});
  query.neighbors().path().toArray();
~ examples.dropGraph("social");
