/**
* A tuple with 5 fields. Tuples are strongly typed; each field may be of a separate type.
* The fields of the tuple can be accessed directly as public fields (f0, f1, ...) or via their position
* through the {@link #getField(int)} method. The tuple field positions start at zero.
*
* Tuples are mutable types, meaning that their fields can be re-assigned. This allows functions that work
* with Tuples to reuse objects in order to reduce pressure on the garbage collector.
*
* Warning: If you subclass Tuple5, then be sure to either
* - not add any new fields, or
* - make it a POJO, and always declare the element type of your DataStreams/DataSets to your descendant
* type. (That is, if you have a "class Foo extends Tuple5", then don't use instances of
* Foo in a DataStream<Tuple5> / DataSet<Tuple5>, but declare it as
* DataStream<Foo> / DataSet<Foo>.)
