Get the Execution Plan from exareme

Start up the exareme console (as described in the Getting started wiki), give a query like the following exaexplainscript 'db:/tmp/exadb' mode:json file '/home/user/simple.dfl';

The hashed string in every node of the plan can be decrypted using the code from here: exareme-master/src/test/java/madgik/exareme/utils/encoding/decryptQuery.java
