  Title   : new()
  Usage   : my $trnascan = Bio::Tools::Run::PiseApplication::trnascan->new($location, $email, @params);
  Function: Creates a Bio::Tools::Run::PiseApplication::trnascan object.
            This method should not be used directly, but rather by 
            a Bio::Tools::Run::AnalysisFactory::Pise instance.
            my $factory = Bio::Tools::Run::AnalysisFactory::Pise->new();
            my $trnascan = $factory->program('trnascan');
  Example : -
  Returns : An instance of Bio::Tools::Run::PiseApplication::trnascan.
