/**
 * RULE #13: do multi-word names match except for
 * one token e.g.
 * "Second Force Recon Company" == "Force Recon Company"
 * Note that this rule has NOT been used in LaSIE's 1.5
 * namematcher
 * Restrictions: - remove cdg first
 *               - shortest name should be 2 words or more
 *               - if N is the number of tokens of the longest
 *                 name, then N-1 tokens should be matched
 * Condition(s): case-sensitive match
 * Applied to: organisation or person annotations only
