    target.insertSubview(subview, belowSubview: sibling)
  elsif (sibling = options[:in_front_of])
    target.insertSubview(subview, aboveSubview: sibling)

end

#constraints(add_to_view = nil, &block) ⇒ Object

Ensure we always have a context in this method; makes it easier to define constraints in an ‘add_constraints` method.
