function data = fixVoltageAnnotations(userdata)
% FIXVOLTAGEANNOTATIONS Fixes the uni/bip reversal identified in
% userdata.electric.voltages in August 2014. This function is not required
% for any userdata .mat files created after 27th August 2014.
%
% Usage:
%   userdata = fixVoltageAnnotations(userdata)
% Where:
%   userdata - is the output
%   userdata - is the input, or 'openfile'
%
% FIXVOLTAGEANNOTATIONS detailed description goes here.
