function [electrodes,manufacturer] = ElectrodeType(number,year)

% Usage: [electrodes,manufacturer] = ElectrodeType(number,year)
%
%   returns the electrode information for Earthscope MT project
%   based on the electrode number and the year in which the data
%   were collected...
%
% Adam's notes as of 2011-06-17:
%
% As far as provenance of electrodes goes, 2006-2009 are all straightforward,
% since we used exclusively one type or another in each successive year.
%
% Starting in 2009 when we switched over to OSU manufactured electrodes,
% we could trace the year of manufacture by the first two digits of the
% electrode serial number. There are some differences in the electrodes
% from one year to the next in terms of minor design variations. So it is
% necessary to refer to the serial number to know the precise type.
