Need to use older versions of panda #54

I am trying the notebook demo simple_synthesis and the 3rd cell gives the following error:

RuntimeError Traceback (most recent call last)

in ----> 1 hh_marg, p_marg, hh_sample, p_sample, xwalk = zs.load_data(hh_marginal_file, person_marginal_file, hh_sample_file, person_sample_file)

RuntimeError: Cannot set name on a level of a MultiIndex. Use 'MultiIndex.set_names' instead.

I am guessing in an older version of pandas the lines below in the function

42: hh_marg.columns.levels[0].name = 'cat_name' 43: hh_marg.columns.levels[1].name = 'cat_values' 49:p_marg.columns.levels[0].name = 'MultiIndex.set_names' 50:p_marg.columns.levels[1].name = 'cat_values'

Removing them seems to cause things to work with Pandas version 1.03.
