[ Maker ] LinkitONE - error : tone was not declared in this scope 錯誤

 Question : LinkitONE - error : tone was not declared in this scope
花了半小時去找去這個問題，終於找出原因，成功的一半，
但還沒完全解決，先分享給大家。

Solved : 
Because the Tone library that you have linked to is not compatible with LinkitOne as it is. It will need modification.

Tone 此函式庫目前不適用於LinkitONE!
