Added some initial thoughts on the interface design to README.
Add skeleton of examples to be included with furious.

Add top level app.yaml, and simple example WSGI app.  This is sufficient
to allow testing from the dev_appserver's shell.
Convert example app.yaml to use include mechanism.

Add webapp WSGI app to webapp helper, and convert included app.yaml to
use bundled include-python27.yaml.
Fix path in include-python27.yaml to match any sub-url.
Merge pull request #1 from WebFilings/initial_design_concept

Some initial thoughts on the interface design to README.
Move run_job to processors module.

Refactor run_job into a processors module to better segregate that code
from the core Async object.  This code will grow into the core job
running logic.
Adjust get_current_context to raise error if not in context.
Add basic structure for callbacks to Async.

Callbacks will be used to specify actions to be performed at given
stages of execution.  This will likely be converted to a concept of
hooks as it progresses.
Clarify unit test docstrs and clarify test name.
Initial sketch of JobContext logic.

The JobContext is used to contain and expose the currently executing
Async object.  This is used to gain access to the Async without the need
to pass it around.
Adjust async run handler to use the JobContext manager.
Add setup and helper to initialize the eniviron with a job context.
Update run_job tests to match new context aware run_jobs.
Add sketch of processor logic to handle job results processing.
Ask git to ignore coverage information.
Add basic nose config to setup.cfg.
Add request_id to local context to ensure the context is reset between requests.
Add missing ContextExistsError exception class.

The ContextExistsError is used to prevent attempts to reinitialize a
context while it is already executing an async job.
Add set_job_context to Async and corresponding unit tests.

The Async object stores a reference to the job context it is running
within.  This makes it possible to access the context, and to prevent
the same job running multiple times.
Add note cautioning against direct import of _local_context.

Directly importing _local_context may result in a reference to the wrong
object being returned if it is imported before being initialized.
