Some query parameter values are numbers and should not be quoted

[fbiville]

See e.g.: neo4j-graph-examples/blank-sandbox#12
A possible solution would be to provide type hint in the parameter definition present in the sandbox own README.adoc attributes.

It currently is defined as:

.Example Query:
[source,cypher,role=query-example,param-name=limit,param-value=10,result-column=count,expected-result=0]
----
MATCH (n)
RETURN COUNT(n) AS count
LIMIT $limit
----

But could become (see param-value-quoted=false - the default would be true):

.Example Query:
[source,cypher,role=query-example,param-name=limit,param-value=10,param-value-quoted=false,result-column=count,expected-result=0]
----
MATCH (n)
RETURN COUNT(n) AS count
LIMIT $limit
----
