1. Fix the mistakes in manual.
2. Fix the bug in the link process of ConvertDataType function.

1. Fix the mistakes in manual. By the way, I have to say there are so many mistakes in the manual. I'm shocked it has been checked a lot of times, but why they are still be there. No one care about that? Really???
2. Clean the codes.

1. Offer CMakeLists.txt to compile the NiuTensor.
2. Update the manuals for CMake.

1. Call the Scale or Shift functions when the parameter shift is 0.0F or scale is 1.0F.
