#error(message, type = :standard, backtrace = nil) ⇒ Object

Patching Object with universally accessible top level error method. The method is used throughout the lib instead of plainly raising exceptions. This allows lib user to easily inject user-specific error handling into the lib by just replacing Object#error method.
