mcilwain	c0f8da0c6e	Switch from Guava Optionals to Java 8 Optionals ... This was a surprisingly involved change. Some of the difficulties included java.util.Optional purposely not being Serializable (so I had to move a few Optionals in mapreduce classes to @Nullable) and having to add the Truth Java8 extension library for assertion support. ------------- Created by MOE: https://github.com/google/moe MOE_MIGRATED_REVID=171863777	2017-10-24 16:53:47 -04:00
