> Currently, an expression and strategy are required to use aggregate().  Perhaps, we could set a default expression (constant(true), etc) and strategy (either groupExchanges() or the attached AggregateAsListStrategy, etc).
> For example, either of these could make a good intuitive default (still requiring a completionSize/Interval, etc)
> aggregate() == aggregate(constant(true)).groupExchanges() 
> or
> aggregate() == aggregate(constant(true), new AggregateAsListStrategy())
> See this discussion for more information....http://camel.465427.n5.nabble.com/Default-Behavior-for-aggregate-td4296790.html
