Text::NASA_Ames::DataEntry - The simples NASA_Ames data-presentation

=head1 SYNOPSIS

 my $de = new Text::NASA_Ames::DataEntry({X => [1,2,3],
                                    V => [3.3,3],
                                    A => [1.4, "S"]});
 my @x = @{ $de->X };

 my @v = @{ $de->V };

=head1 DESCRIPTION

A dataentry consists of the independent variables X, the auxiliary
variables A, and the primary dependent variables V.
