/*
<< .Object.Property >>

Property can be a attribute or a method both used without ()
Please also note the initial dot .

Currently there are following objects that can be used:

Account -  the account that this action is called on
Action - the action with all it's attributs
Actions - the list of actions in the current action set
Sq - StatsQueueTriggered object

We can actually use everythiong that go templates offer. You can read more here: https://golang.org/pkg/text/template/
