Feature Request

We would like to be able to do the following

import opendssdirect as dss
print(dss.dss_lib.__version__)

[kdheepak]

This feature will be available when dss_python>=v0.10.0 is available.

That's directly the lower-level CFFI lib.
We can leave a reference to the full dss_python module though.

I'll try to add a proper version in the Pascal function too (https://github.com/PMeira/dss_capi/blob/master/src/v7/CAPI_DSS.pas#L48).

[kdheepak]

Yes you are right.

dss._utils.dss_py.__version__

When this is available, we want to expose it in a nicer manner in OpenDSSDirect.py. We can add a function that prints the version number of dss_python, dss_capi and electricdss-src. We don't even necessarily need a version number for the dss_capi and electricdss-src if we can get the commit hash or git-tree hash that was used to build the package.
