Do we need MapProcessor/MapFunction as it looks very similar to each
operation (EachProcessor)?
```java
public Stream each(Fields inputFields, Function function, Fields
functionFields)
public Stream each(Function function, Fields functionFields)
```
Agree with @ptgoetz on filter.
Good to have flatMap operation.
> Add map, flatMap and filter operations in trident api

> map and flatMap are common stream operations.
> Right now in trident this has to be implemented via each() which also sends
> the input field values in addition to the mapped field values, so the map and
> flatmap should make things slightly more efficient and easy.
