=head1 NAME
Bio::Tools::Run::Phylo::Hyphy::REL - Wrapper around the Hyphy REL analysis
=head1 SYNOPSIS
use Bio::Tools::Run::Phylo::Hyphy::REL;
use Bio::AlignIO;
use Bio::TreeIO;
my $alignio = Bio::AlignIO->new(-format => 'fasta',
-file => 't/data/hyphy1.fasta');
my $aln = $alignio->next_aln;
my $treeio = Bio::TreeIO->new(
-format => 'newick', -file => 't/data/hyphy1.tree');
my $rel = Bio::Tools::Run::Phylo::Hyphy::REL->new();
$rel->alignment($aln);
$rel->tree($tree);
my ($rc,$results) = $rel->run();
=head1 DESCRIPTION
This is a wrapper around the REL analysis of HyPhy ([Hy]pothesis
Testing Using [Phy]logenies) package of Sergei Kosakowsky Pond,
Spencer V. Muse, Simon D.W. Frost and Art Poon. See
http://www.hyphy.org for more information.
This module will generate the correct list of options for interfacing
with TemplateBatchFiles/Ghostrides/Wrapper.bf.

=head2 Support
Please direct usage questions or support issues to the mailing list:
I<bioperl-l@bioperl.org>
rather than to the module maintainer directly. Many experienced and
reponsive experts will be able look at the problem and quickly
address it. Please include a thorough description of the problem
with code and data examples if at all possible.

=head2 valid_values
Title : valid_values
Usage : $factory->valid_values()
Function: returns the possible parameters
Returns: an array holding all possible parameters. The default
values are always the first one listed. These descriptions are
essentially lifted from the python wrapper or provided by the author.
Args : None

=head2 new
Title : new
Usage : my $obj = Bio::Tools::Run::Phylo::Hyphy::REL->new();
Function: Builds a new Bio::Tools::Run::Phylo::Hyphy::REL object
Returns : Bio::Tools::Run::Phylo::Hyphy::REL
Args : -alignment => the Bio::Align::AlignI object
-save_tempfiles => boolean to save the generated tempfiles and
NOT cleanup after onesself (default FALSE)
-tree => the Bio::Tree::TreeI object
-params => a hashref of parameters (all passed to set_parameter)
-executable => where the hyphy executable resides

=head2 run
Title : run
Usage : my ($rc,$results) = $rel->run($aln);
Function: run the rel analysis using the default or updated parameters
the alignment parameter must have been set
Returns : Return code, Hash
Args : L<Bio::Align::AlignI> object,
L<Bio::Tree::TreeI> object [optional]

=head2 create_wrapper
Title : create_wrapper
