PyOphidia to load client credentials from env if not given

[TobiasWeigel]

When creating a client instance, user credentials and server details need to be specified:

ophclient = client.Client(username="oph-user",password="oph-passwd",server="127.0.0.1",port="11732")

For ecaslab, these details are already known to the executing environment, because the user is logged in to Jupyter and the server may also be set to a default, at least for novice users. Would it be possible to let the client read these options from sys.env if they are not given? The Ophidia terminal is able to do this already.

This feature was under development and is now available in PyOphidia v1.6.0 (PR #17). The connection parameters can be read directly from environment variables, similarly to the Ophidia Terminal. The connection command to exploit this feature is:

ophclient = client.Client(read_env=True)
