export of Cypher for Neo4j does not have all the data present in `data.json`

[bhpayne]

On the https://derivationmap.net/navigation page, the "export to Cypher" option produces a plain text Cypher file for Neo4j that lacks some data present in data.json.

The function where the fix is needed is def convert_data_to_cypher in https://github.com/allofphysicsgraph/proofofconcept/blob/gh-pages/v7_pickle_web_interface/flask/compute.py

For example, the exported Cypher file does not include

• the SymPy AST text
• any symbol ID information
