Review Comment:
@swaminathanmanish is your idea to change the signature as follows:
```
public Object aggregate(Object value1, Object value2, Object
functionParameters)
```
And then each `ValueAggregator` subtype casts this Object to a concrete and
more specific type? To my knowledge, there is no other general purpose type
that can be used across all ValueAggregators since each ValueAggregator will
have its own function parameters.
It would help to flesh out your idea a little more so that I can try it out.
