"""Defines all the valid streams that clients can subscribe to, and the format

Each stream is defined by the following information:

    stream name:        The name of the stream
    row type:           The type that is used to serialise/deserialse the row
    current_token:      The function that returns the current token for the stream
    update_function:    The function that returns a list of updates between two tokens
