Version 1.2.0

• Added Java 8 support. Added new MapElements and FlatMapElements transforms that accept Java 8 lambdas, for those cases when the full power of ParDo is not required. Filter and Partition accept lambdas as well. Java 8 functionality is demonstrated in a new MinimalWordCountJava8 example.
• Enabled @DefaultCoder annotations for generic types. Previously, a @DefaultCoder annotation on a generic type was ignored, resulting in diminished functionality and confusing error messages. It now works as expected.
• DatastoreIO now supports (parallel) reads within namespaces. Entities can be written to namespaces by setting the namespace in the Entity key.
• Limited the slf4j-jdk14 dependency to the test scope. When a Dataflow job is executing, the slf4j-api, slf4j-jdk14, jcl-over-slf4j, log4j-over-slf4j, and log4j-to-slf4j dependencies will be provided by the system.
