Feature request: turn off echo

[victoriastuart]

Hi Nicole!

Can we turn off / disable the echoing of the cypher script contents during the script executions, e.g. as shown in my comment here? :

neo4j/neo4j#5901 (comment)

That issue also raises the subject of the commenting of cypher statements in cypher scripts, which throws errors in Cycli (but not cypher-shell). I believe that is a Neo4j issue (hence, my post there)?

Thanks again for all your work; e.g. #60 -- I am thrilled that you continue to support Cycli, which is the best cypher CLI, IMO. :-D

This PR #63 should add echo toggling (when combined with -f) - but it's not yet ready for merging with master!
