% loadeep_avg() - Load an averaged ANT EEP file (*.avr).
%
% Usage:
%   >> [eep] = loadeep_avg(file);
%
% Inputs:
%            filename    - name of averaged ANT EEP file, including extension (*.avr)
%
% Outputs:
%   [eep]                - data structure holding continous EEG information and other
%                          relevant information.
