Move getXXX functions to methods

[jun9358]

I want to override functions(getScrollParent, getCurrentDistance) using extends options (http://vuejs.org/v2/api/#extends)
(For non-scrolling iframe support - use scrollParent to iframe's parent body, but i think this is not good idea support it basically in this library)

So, could you move these functions to vuejs' methods?

Sounds a good idea! I will move functions to methods in the next version. For now, this part of the documentation maybe useful for you.

I forked and moved those functions, and using it now.
Thank you for accepting my suggestion.
