-=head1 NAME

-  Bio::EnsEMBL::Utils::Iterator
-
-=head1 SYNOPSIS
-
-  my $variation_iterator = $variation_adaptor->fetch_iterator_by_VariationSet($1kg_set);
-
-  while (my $variation = $variation_iterator->next) {
-    # operate on variation object
-    print $variation->name, "\n";
-  }
-
-
-=head1 DESCRIPTION
-
-  Some adaptor methods may return more objects than can fit in memory at once, in these cases 
-  you can fetch an iterator object instead of the usual list reference. The iterator object 
-  allows you to iterate over the set of objects (using the next() method) without loading the
-  entire set into memory at once.
