PDF OF PUBLISHED PAPER HERE

A corrected version of the published paper has been prepared (OCR of PDF to Word, editing,  then back to PDF). In addition to correcting all the errata discovered to date (2/2/17)
this version also changes the punctuation of the original away from that insisted on by the JNCS publisher. Most of these changes remove or add periods, commas and hyphens and
capitalize section titles. Additional typos have also been corrected. Apart from the punctuation changes all corrections are indicated in red. None of the scientific content has been
updated or modified  - this is not a "2nd Edition". Be aware that despite exhaustive checking the copying and editing may have introduced some additional errors - thus the following link
is to a First Draft that may be modified again. PDF file of modified manuscript HERE.
