import_from_df

This function only works with localhost Neo4j instances.

The aim of neo2R is to provide simple and low level connectors
for querying neo4j graph databases (<https://neo4j.com/>).
The objects returned by the query functions are either lists or data.frames
with very few post-processing.
It allows fast processing of queries returning many records.
And it let the user handle post-processing according to the data model
and his needs.
