Edge Retrieval

/*
For example, consider I have in Graph Schema the Vertex Person has an Edge to Vertex Phone called "HAS_PHONE"

If I wanted to get that edge, here is how that would look.

/*
Moreover, the Target Vertex is actually optional. If I don't pass anything to the target vertex parameter,
The call will return all edges stemming from the "source" that are of passed in edge
