Noise Generator Node

I was thinking about a way to quickly port noise maps to blender. This would make it possible to create his own noise textures, or port them from the internet, games, or other software.

A simple way to make this would be to create a noise node, where you can input the amount of octaves, the amplitude and the frequency of the sine curve(s) and the node would combine them with:

y=y1(sincurve1)+y2(sincurve2)...

There should also be a way to decide how many dimensions the custom noise map uses.

I´m sure there are still some things, that are necessary to port noises to blender and i still know relatively little how this works, so if I have forgotten anything, just comment.
