  14 =head1 NAME
  15
  16 Bio::Search::Hit::HitFactory - A factory to create Bio::Search::Hit::HitI objects
  17
  18 =head1 SYNOPSIS
  19
  20     use Bio::Search::Hit::HitFactory;
  21     my $factory = Bio::Search::Hit::HitFactory->new();
  22     my $resultobj = $factory->create(@args);
  23
  24 =head1 DESCRIPTION
  25
  26 This is a general way of hiding the object creation process so that we
  27 can dynamically change the objects that are created by the SearchIO
  28 parser depending on what format report we are parsing.
  29
  30 This object is for creating new Hits.
