-- change scope of junit to test
-- reformat java source code
-- extend Task with a resumeExecution() method to execute synchronously
  - we do not care about pause reasons
  - we care about any locks held
-- added getter for exitReason in TaskDoneReason
-- example which uses resumeExecution()
-- disallow instantiation of kilim Scheduler
-- disallow instantiation of kilim WorkerThread
-- fix reference to exitObj
-- added todo to minimize overhead
-- isDone() is no longer synchronized
-- change the delimitation method name to resumeExecution
-- delete nio and http packages
-- delete redundant clsses for our use-case:
 - Cell
 - Mailbox
 - Scheduler
 - TaskGroup
 - WorkerThread
-- reformatted code in bench directory
-- rename jar to kilim-weaver
-- reformat build.xml
-- ensure weaveClass() does weaving!
