% PURPOSE  : 	Clear Artifact Detection marks on EEG
% 
% FORMAT   : 
% 
% >> EEG = pop_resetrej(EEG, arjm, bflag)
% 
% EXAMPLE  :
% 
% EEG = pop_resetrej(EEG, 1, 10312);
% 
% INPUTS   :
% 
% Arjm          - 1- Reset EEGLAB Artifact Detection Mark
%                 0- Do not reset EEGLAB Artifact Detection
% Bflag         - numbers correspond to which User flags and Artifact flags are	
%                 marked
% 
% OUTPUTS  :
% 
% Outputted dataset with artifact detection marks cleared
