[wildfly-dev] Analyse the management model

[Harald Pehl]

Comparisons are atm only possible by saving the results to a text file
and by using external diff tools. To save the attributes of a resource
one would use something like

MATCH (r:Resource)-->(a:Attribute)
WHERE r.address = "/subsystem=elytron/authentication-context=*"
RETURN a
