% CHECKLABSYNTAX Check the syntax of all chords in a lab file
% 
% [success] = checklabsyntax(labfile, {fid})
% 	
% Checks syntax of all chord symbols in a lab file. Any incorrect chords 
% will produce syntax errors and be quoted with time of chord from the 
% labfile given for inspection.
% 
% fid is the file id of the output log file.  If not given, the error log 
% will be printed to the screen
% 
% Success = 1 if all symbols have correct syntax, 0 otherwise.
%
% Returns: success (boolean)
