function str = finish(str,unknowns)
%TEMPLATE/FINISH Apply given strategy to unknown fields in a string
%  STR = FINISH(STR,UNKNOWNS) applies on string STR the strategy defined
%  in UNKNOWNS to unknowns fields '{UNKNOWNS_FIELDS}'.
%  UNKNOWNS may be:
%    * 'keep' to do nothing
%    * 'remove' to remove all undefined fields
%    * 'comment' to replace undefined fields by a warning HTML comment.
%  This function uses Matlab REGEXPREP function coming with R13. If you
%  hold an older version, please comment lines 38 and 42: then you can 
%  only apply the 'keep' strategy.
