Review request for atlas, Madhan Neethiraj, Nikhil Bonte, Nixon Rodrigues,
Sarath Subramanian, and Sidharth Mishra.
Bugs: ATLAS-3762
https://issues.apache.org/jira/browse/ATLAS-3762
Repository: atlas
Description
-------
**Problem Definition**
Please refer to JIRA for details.
**Updates**
- Modifed: _AtlasJanusGraph.wrapVertices_ and _AtlasJanusGraph.wrapEdges_ : Now
uses genuine iterators. This reduces number of elements fetched, since the
search is linear.
- New: _AtlasVertex.getEdgeCount_ fetches edge count using iterator returned
from _JanusVertex_. Fetching the count is effecient using stream support.

Testing
-------
**Volume testing**
High volume testing makes the edge fetching effcient. Cases where incoming
edges was in 1000s and outgoing edges was handful.
Memory footprint has improved since JanusGrpah caches edges and then expires
it. Fetching fewer edges will reduce number of items in memory.
