Example of usage

The following example shows the use of evc through the Python interactive shell:

First, run the server "Eve"

    Python 2.7.5 (default, Mar  9 2014, 22:15:05)
    [GCC 4.2.1 Compatible Apple LLVM 5.0 (clang-500.0.68)] on darwin
    Type "help", "copyright", "credits" or "license" for more information.
    >>> from eve import Eve
    >>> settings = {'XML': False, 'JSON': True, 'SERVER_NAME': '127.0.0.1:5555', 'MONGO_DBNAME': 'evc_test'}
    >>> settings['RESOURCE_METHODS'] = ['GET', 'POST', 'DELETE']
    >>> settings['ITEM_METHODS'] = ['GET', 'PATCH', 'PUT', 'DELETE']
    >>> settings['DOMAIN'] = {'persons': {'versioning': True, 'allow_unknown': True, 'schema': {}}}
    >>> app = Eve(settings=settings)
    >>> app.run()
     * Running on http://127.0.0.1:5555/ (Press CTRL+C to quit)

Second, run the client "Evc"

    Python 2.7.5 (default, Mar  9 2014, 22:15:05)
