Description

Quality of life changes based on initial feedback. Main changes are:

1. onCreate Map will now inherit from main merge argument, and overrides of existence criteria (id/label/in/out) will be prohibited.
2. Direction.IN/OUT can be specified by additional options (Merge.inV/outV), which can take Map arguments, or a traversal which results in a Vertex.
3. mergeE will no longer accept upstream Vertices as arguments for Direction.IN/OUT where not specified in the map arguments.
