AttributeError: 'NoneType' object has no attribute 'values'

[HaihuiZhang]

Dear Administrator,
An 'AttributeError' occurred when I run 'espei --input espei-in-2.yaml' using the latest development version of ESPEI. Would you mind help me to check my dataset? Thanks.

My pycalphad also used the latest development version.

At the same time, I use the latest development version to run the successful case that I ran before using espei = 0.7.2, pycalphad = 0.8 also reported an error called KeyError: 'BLANK'. So maybe there is a problem with the latest version.

This should be fixed #133
