def create attributes = nil, options = {}, &block
  if attributes.is_a?(Array)
    attributes.collect { |attr| create(attr, options, &block) }
  else
    object = new(attributes, options)
    yield(object) if block_given?
    object.save
    object
  end

#destroy(&block) ⇒ Object

def destroy &block
  self._destroy = block if block_given?
end

#find(id_ = nil, &block) ⇒ Object

When a block is passed, that block is set to _find. When id_ is passed (or no block is passed) a new record is instantiated with the passed id_ and the _find block is called. If the return from the _find block is nil or false, a ResourceNotFound error is raised.
