Description: geteventstore ========================

    This is a simple implementation of the Event Store client for the HTTP interface. It uses asyncio to asyncly parse events
    
    ## Reference
    
    Accessing the Event Store
    
    ### Client
    
    `Client(options) -> client`
    
    Creates a new event store client. The keyword arguments are:
    
    - `host`: host of the RethinkDB instance. The default value is `localhost`.
    - `port`: the driver port, by default `2113`.
    - `loop`: the asyncio event loop, by default `asyncio.get_event_loop()`
    
    *Example*: Create a new client to the default event store
    
    ```python
    loop=asyncio.get_event_loop()
    client = geteventstore.Client(loop=loop)
    ```
    
    ### stream_reader
    
    `client.stream_reader(options) -> Reader`
    
    Creates a stream reader. The keyword arguments are:
    
    - `stream`: the stream to read from.
    
    *Example*: Create a new stream readers
    
    ```python
    import geteventstore
    import asyncio
    
    async def test(loop):
        try:
            current = 0
            poll = 10
            while True:
                current = await get_events(loop, current, poll)
        except KeyboardInterrupt:
            return
    
    async def get_events(loop, current=0, poll=0):
        client = geteventstore.Client(loop=loop)
        reader = client.stream_reader('flyers')
        reader.next_version = current
        if poll > 0:
            reader.long_poll(poll)
    
        async for event, meatadata, updated in reader:
            print(event)
            print(metadata)
            print(updated)
        return reader.next_version
    
    if __name__ == '__main__':
        loop = asyncio.get_event_loop()
        loop.run_until_complete(test(loop))
    ```
    
    ### Reader
    
    `geteventstore.Reader(options) -> Reader`
    
    Creates a stream reader. The keyword arguments are:
    
    - `stream`: the stream to read from
    - `client`: the geteventstore client
    - `feed_parser`: the feed parser to use, defaults to `feedparser`. Must be compatible with feedparser
    - `http`: the http client to use, defaults to `aiohttp`. Must be compatible with aiohttp
    
    *Example*: Create a new stream and read from *text*
    
    ```python
    import geteventstore
    import asyncio
    
    async def test(loop):
        try:
            current = 0
            poll = 10
            while True:
                current = await get_events(loop, current, poll)
        except KeyboardInterrupt:
            return
    
    async def get_events(loop, current=0, poll=0):
        client = geteventstore.Client(loop=loop)
        reader = geteventstore.Reader('flyers', client)
        reader.next_version = current
        if poll > 0:
            reader.long_poll(poll)
    
        async for event, _, updated in reader:
            print(event.id)
            print(updated)
        return reader.next_version
    
    if __name__ == '__main__':
        loop = asyncio.get_event_loop()
        loop.run_until_complete(test(loop))
    ```
