coreapi client - Transports section in docs/topics/api-clients.md

[2ynn]

Hi,

Following the Transport section in the docs https://github.com/encode/django-rest-framework/blob/master/docs/topics/api-clients.md#transports

transports = transports.HTTPTransport(credentials=credentials)
client = Client(transports=transports)

leads to an error stating that transports are not itterable.

In the coreapi documentation: https://github.com/core-api/python-client/blob/master/docs/api-guide/client.md#instantiating-a-client
transports are defined as an array:

transports = [
    transports.HTTPTransport(auth=auth, session=session)  # http, https
]
