> Sometimes the kind of computations one wants to perform in startBundle depend on side
inputs (and, implicitly, the window). For example, one might want to initialize a (non-serializable)
stateful object. In particular, this leads to users incorrectly (in the case of triggered
or non-globally-windowed side inputs) memoizing this computation in the first processElement
call. 
> One option would be to fold this into a customizable ViewFn.
