KinoSearch1::Analysis::Stopalizer - suppress a "stoplist" of common words

new
           my $stopalizer = KinoSearch1::Analysis::Stopalizer->new(
               language => 'de',
           );

           # or...
           my $stopalizer = KinoSearch1::Analysis::Stopalizer->new(
               stoplist => \%stoplist,
           );

       new() takes two possible parameters, "language" and "stoplist".  If "stoplist" is supplied, it will be
       used, overriding the behavior indicated by the value of "language".

       •   stoplist - must be a hashref, with stopwords as the keys of the hash and values set to 1.

       •   language   -  must  be  the  ISO  code  for  a  language.   Loads  a  default  stoplist  supplied  by
           Lingua::StopWords.

       A "stoplist" is collection of "stopwords": words which are common enough to be of little value when
       determining search results.  For example, so many documents in English contain "the", "if", and "maybe"
       that it may improve both performance and relevance to block them.

           # before
           @token_texts = ('i', 'am', 'the', 'walrus');

           # after
           @token_texts = ('',  '',   '',    'walrus');
