Assertation error on connection

[tfrojd]

I run ib_insync on an anaconda installation (python 3.6) on Debian.

from ib_insync import *
ib = IB()
ib.connect('ip_here', portno, clientId=12)

I then get the following error:

--------------------------------------------------------------------------

AssertionError: To allow nested event loops, use util.patchAsyncio()

Any ideas why this happens?

Figured it is because I the example is not made to run in a notebook but only from a script.

It is clear from the example notebook but maybe a more informative error messsage or mentioning this with the README.md example would save other beginners some time.

I've updated the readme code example to include util.startLoop(), like in the notebook examples.
