#wrap method to wrap error

[greyblake]

It would be cool to have #wrap or #chain method to wrap error instead of passing it to new.

Example

class MyError
  include Nesty::NestedError
end

begin 
  boooom!
rescue NoMethodError => original_error
  my_error = MyError.custom_method_to_build_error_message(with, number, of, parameters)
  my_error.wrap(original_error)  # That's where I would like to use it
  raise my_error
end

Also I can pass original_error to MyError.custom_method_to_build_error_message as additional parameter but I would prefer avoid doing this to not overload interface with parameters and to make it more reusable.

Thanks.

I know that by default it picks the last error using $! variable, but want to do it in more verbose way not confuse my colleagues:)
