How to Change Default Navigation Controls?

Hi there,

I'm new to jME but have decent 3D knowledge in general. and I want to change the default navigation buttons for SimpleGame to be more like the normal scientific 3d applications (left mouse rotate, right pan, zoom with the while) more like examples in

I know that I can override the defaults, but I wonder if there is a ready class (or someone already did it) where I can just extends that has this kind of navigation nature. I'm not using jME as a gaming engine, but rather to boost my development for a quick 3D scientific prototype app.

Thanks in advance,
