tone.h
Written by Leong Kum Loong.
20 Nov 2017, REV. 2
All routines and functions in this library are written by me solely with the purpose
of implementing an identical "tone" library that was introduced by Arduino IDE.
Example reference from Github
===============================
The mario_example routine "notes" are reference to the work of Gregory Kielian.
The starwars_example routine "notes" are reference to the work of nicksort.
