Subject [jira] [Updated] (CRUNCH-489) Add methods to create PCollections from Java Iterable to Pipeline interface

Josh Wills updated CRUNCH-489:
------------------------------
    Attachment: CRUNCH-489c.patch

Latest cut at this, which I'm happier with-- I changed the create() interface to be one of:

PCollection<T> create(Iterable<T>, PType<T>)
PCollection<T> create(Iterable<T>, PType<T>, CreateOptions)
PTable<K, V> create(Iterable<Pair<K, V>>, PTableType<K, V>)
PTable<K, V> create(Iterable<Pair<K, V>>, PTableType<K, V>, CreateOptions)

...where CreateOptions can hold a name for the new PCollection and a parallelism level to
use (which we may ignore, depending on the Pipeline type.)

I think that to make this work, I need to add a read() method that can take in not only a
Source, but also a name that we want to give the resulting PCollection, which seems like a
generally useful thing. Thoughts [~gabriel.reid] ?

(Oh yes, and I need to add a Scala interface for [~davw].)
