%NOTES2PITCHCLASSES convert a note list to an array pitchclasses

% [pitchclasses, success, errormessage] = notes2pitchclasses(notes, {verbose})
% 
% Converts a cell array of note strings to an array of pitch class integer 
% values. Pitch class values are referenced w.r.t. C = 0. 
% 
% Success = 1 if symbols converted correctly, 0 otherwise.
% 
% If optional argument 'verbose' is 1, function prints any errormessage to 
% the screen.
% 
% calls note2pitchclass
% 
% returns:  pitchclasses (array of integers)
