Subject: Changed scoring, including adding code to compute string differences.
 Turned off line length checking. New scores:
 ['(583,sha1:K2DKSSVTXWPRMFDTWSTCQW3RVWRIOV3Q,DOI-0,'title 1','title 1:
 tng')'] ['(500,sha1:K2DKSSVTXWPRMFDTWSTCQW3RVWRIOV3Q,DOI-0.5,'title 1','title
 1: tng 2')'] ['(500,sha1:K2DKSSVTXWPRMFDTWSTCQW3RVWRIOV3Q,DOI-0.75,'title
 1','title 1: tng 3')']
 ['(588,sha1:C3YNNEGH5WAG5ZAAXWAEBNXJWT6CZ3WU,DOI-1,'title 2: tng','title 2:
 rebooted')']
