Hi all This question seems kind of dumb, but I cannot find the way to to this operation when the vector is a Point object (for the case of the face normals). I've seen in the file tensor_tools.h there are several functions for inner products with TypeVector, but I cannot find a dot product of a TypeTensor and a TypeVector. I think I could use the function vector_mult in the class DenseMatrix, but I would have to copy the object Point values to a DenseVector object. Is there a better way to do this? Also, there seems to be two families of vector/matrices data structures. One the TypeVector/TypeTensor and the DenseVectorBase/DenseMatrixBase, what is the reason behind this design?
