Arduino Due libraries (official and 3rd party)

Hi!
As i like libraries, i have done one for Timers on the Arduino DUE.

You can check it out here: GitHub - ivanseidel/DueTimer: ⏳ Timer Library fully implemented for Arduino DUE

All 6 timers are fully implemented, and ready to play with...

May I ask you how I can use your file? I cannot include any library from out side. Is there anyway to run within one file? I would like to use a timer and change the REG by Serial Monitor.
