Issue with numpy_minmax_scaler unittest

[sgoldenCS]

When I run the unittest for the numpy_minmax_scaler, I get the following error output:

***************************************

***   Info: NumpyMinMaxScaler   ***
Input(s):
i) Full path to .yaml configuration file 
ii) Optional: User configuration, i.e. a python dict with additonal / alternative settings
iii) Numpy data
What this module does:
i) Scale input data with respect to a specified range
ii) Optional: reverse the scaling
Output(s):
i) Scaled .npy data
ii) Optional: unscaled .npy data
Note(s):
i) The scaler will (by default) be fitted to the data and the transform it. To disable the fitting, do: run(data,disable_fit=True)

Oh, I've figured it out. It expects you are running the unit test from jlab_datascience_core/utests instead of just jlab_datascience_core. It would be nice if this could be made to work without requiring the tests to run from a particular directory.
