Bio::EnsEMBL::DBSQL::RegulatoryFeatureAdaptor
=head1 SYNOPSIS
$rfa = $database_adaptor->get_RegulatoryFeatureAdaptor();
my $regulatory_feature = $rfa->fetch_by_dbID(1234);
=head1 DESCRIPTION
This is an adaptor for the retrieval and storage of RegulatoryFeature objects
from the database. Most of the implementation is in the superclass BaseFeatureAdaptor.

=head2 fetch_all_by_Slice
Arg [1] : Bio::EnsEMBL::Slice $slice

regulatory features of all analysis types are retrieved.
Example : @rfeats = @{$rfa->fetch_all_by_Slice($slice, 'miRanda')};
Description: Retrieves regulatory features overlapping the area designated by
the provided slice argument. Returned features will be in
in the same coordinate system as the provided slice and will
have coordinates relative to the slice start.
