=head1 NAME

Bio::DB::SeqFeature::NormalizedFeatureI -- Interface for normalized features

=head1 SYNOPSIS

none

=head1 DESCRIPTION

This is an extremely simple interface that contains a single method,
subfeatures_are_normalized(). This method returns a true value.

Bio::DB::SeqFeature::Store feature classes will inherit this interface
to flag that they are able to store subfeatures in a normalized way
such that the subfeature is actually contained in the
Bio::DB::SeqFeature::Store database and the parent feature contains
only the subfeatures primary ID.

=head1 BUGS

None, but the whole class design might be flawed.
