=head1 NAME
Test2::Compare::Ref - Ref comparison
=head1 DESCRIPTION
Used to compare two refs in a deep comparison.
=head1 SYNOPSIS
my $ref = {};
my $check = Test2::Compare::Ref->new(input => $ref);
# Passes
is( [$ref], [$check], "The array contains the exact ref we want" );
# Fails, they both may be empty hashes, but we are looking for a specific
# reference.
is( [{}], [$check], "This will fail");
