=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");
