Ovf file structure description
Created by: ax-meyer
I added an description for the OVF File structure so that someone else could implement a compatible reader / writer in another language.
Furthermore, added checks & conversion in the C# code to make sure that the LUT indices are always written as LittleEndian.

Can you (or the Hiwi who implemented the simultaneous reading / writing of WorkPlanes for the file structure) sanity check my description? Since I didn't implement it, I reconstructed it from the code, I may still have gotten something wrong in the logic there.
