tsunami interface beginnings

Thanks to blueb for getting me started,
I modified your code and added some functions.
It took me a while to get the Structure/Pointer stuff figured out.
Anyways here is my tsunami.pbi include file, feel free to help out and add to it. Also blueb ihanged your constant names so they would match the manual, I hope you dont mind.
