% mff_export - export EEGLAB structure to MFF file. This function calls
%                 all other function to create MFF structure, export
%                 events, channels and channel coordinates.
%
% Usage:
%   mff_export(EEG, mffFile);
%
% Inputs:
%  EEG     - EEGLAB structure
%  mffFile - filename/foldername for the MFF file (MFF file/folder must
%            already exist)
