    This Javascript is used for the eLibrary module for article pages.
    It extracts the NYT keywords from %%KEYWORDS%% and dynamically writes a 
    bulleted list of search terms for HighBeam
    
    02/04/04: original file created
    02/05/04: added ability to omit "bad" keywords"
    02/19/04: apply redesigned template
    03/03/04: per client's request, start from 2nd keyword. Make appropriations
              for when there are no eligible results.
