* Hash source code into function ID to reduce likelihood of collisions.
* Fix failure test example.
* Replace assertTrue with assertIn to improve failure messages in tests.
* Fix failure test.
* Implement actor field for tasks
* Implement actor management in local scheduler.
* initial python frontend for actors
* import actors on worker
* IPython code completion and tests
* prepare creating actors through local schedulers

* get rid of export synchronization
* update
* insert actor methods into the queue in the right order
* remove print statements
* make it compile again after rebase
* Minor updates.
* fix python actor ids
* Pass actor_id to start_worker.
* add test
* Minor changes.
* Update actor tests.
* Temporary plan for import counter.
* Temporarily fix import counters.
* Fix some tests.
* Fixes.
* Make actor creation non-blocking.
* Fix test?
* Fix actors on Python 2.
* fix rare case.
* Fix python 2 test.
* More tests.
* Small fixes.
* Linting.
* Revert tensorflow version to 0.12.0 temporarily.
* Small fix.
* Enhance inheritance test.
* Remove start_ray_local from ray.init and change default number of workers to 10.
* Remove alexnet example.
* Move array methods to experimental.
* Remove TRPO example.
* Remove old files.
* Compile plasma when we build numbuf.
* Address comments.
* Update worker code and services code to use plasma and the local scheduler.
* Cleanups.
* Fix bug in which threads were started before the worker mode was set. This caused remote functions to be defined on workers before the worker knew it was in WORKER_MODE.
* Fix bug in install-dependencies.sh.
* Lengthen timeout in failure_test.py.
* Cleanups.
* Cleanup services.start_ray_local.
* Clean up random name generation.
* Cleanups.
* Revert "Make tests more informative (#372)"
This reverts commit fd353250c8.
* fix bugs, in particular deactivate worker service on driver and remove condition variables
* changes to minimize the changes in this PR
* switch from faulty mutex synchronization to using atomics
* Increase the default size of the message queues, to accommodate exporting large numbers of remote functions. This is a temporary fix, but not a long term solution.
* Reorganize the scheduler export code to queue up exports. This does not solve the underlying problem yet, but sets up a solution.
* Start a separate thread on driver to print error messages by constantly querying the scheduler. This is a temporary solution because the solution based on starting a worker service for the driver which the scheduler can push error messages to is buggy.
* Fix segfault in taskcapsule destructor.
* Move tests for catching errors into a separate test file.
* Revert "roll back grpc (#368)"
This reverts commit c01ef95d04.
