v1 of getGOcodes

% This function takes a list of UniProt IDs of interest as well as the
axes
% and GOArray matrices.  The function sequentially finds the GO codes of
% each UniProt ID and stores the information in a Map structure.  The
keys
% are the GO IDs found and the values are a 1 x 2 cell array, containing
in
% the first cell the annotation and the total incidence of said GO ID
% within the list of UniProt IDs in the 2nd cell.  For example: key =
% GO:99999999, value = {'unknown function',2}, given that two proteins
have
% the GO ID GO:99999999
