Unable to import python script from a second package

I am attempting to import a python script which is part of a second package. The code for my project is located at https://github.com/Aditya90/zeroborgRobot/tree/feature/AddZeroborgLibrary. In the file `node_zeroborg_output.py`, I am attempting to import the `zeroborg_output.zeroborg` script which has the `ZeroBorg` class. When I try running `node_zeroborg_output`in the package `robot_motion_control`, I get the following error ``` ImportError: No module named zeroborg_support.zeroborg ``` I am new to ROS, so I might be missing something obvious. Thank you for the help.
