Cannot find SimpleSpline Class

I am very new to Ogre and working on learning how to use it but I've run into a problem. I am developing in C# using OgreDotNet and am trying to translate the Fresnels demo that is in c++ into C#. My problem is at this line in the C++ code:

SimpleSpline fishSplines[NUM_FISH];

I cannot find this SimpleSpline class anywhere in OgreDotNet. I have searched everywhere I can find. Is this something that hasn't been implemented yet? If not where can I find it? My knowledge of C++ is pretty limited so maybe this is a stupid question, but if it is please point me in the right direction...

Thanks

It might be there, I'm not sure... However, I think you will have better luck using MOGRE as it is more actively maintained/supported. Although, it currently only works under Win32 & .Net 2.0.
