% GUI_EEG_ASCII_PARAMETERS - Define EEG ascii parameters
% 
% Useage: [GUI] = gui_eeg_ascii_parameters(parentgui)
%
% parentgui     - is a handle to the parent gui that calls
%                 this gui; it will contain a userdata property
%                 that contains the p structure
%
% In the event that the parentgui doesn't contain the p
% struct, this function calls eeg_toolbox_defaults 
% to create the p struct.
%
% The GUI return value is a handle to this gui (useful in
% 'waitfor' commands) and p is as above.  This function can
% update the p struct of the parentgui userdata too.
