Change our versions to 2.0.0-SNAPSHOT for the start of a branch for the 2.0.0 release...once we get closer this will be merged into unstable_staging (and then eventually master)
Removed some of the deprecated features for the 2.0.0 release
This is removal for issues: #67 #66 #65
Merge branch 'v2.0.0_staging' into SingleThreadedScheduler
