First attempt at "sample" operator. Should probably use "interval"
operator instead of an internal clock. Also still needs tests!
Added a scheduler for scheduling actions on the Swing event thread.
Merge branch 'interval' into sample
Switched sample from internal clock to using the interval operator
Added a unit test against the sample operator
Merge branch 'master' into sample
added missing linebreak
Merge branch 'master' into SwingScheduler
adapted SwingScheduler to new Scheduler interface
minor renaming and removing unnecessary warning suppression again
fixed formatting and removed superfluous checks
Added value class wrapping timestamped values
Added toString to Timestamped
added copyright text to Timestamped class, added timestamp operation, reusing mapping
Removed superfluous null check
Added `timestamp` method to `Observable`, too.
Merge remote-tracking branch 'parent/master' into timestamp
Merged with master from Netflix repo.
Merge branch 'master' into sample
Added sample methods to observable.
