Convert vector of vectors or array of pointer of pointers to numpy array and back #7
Description
To enable pickling, we basically need to convert proj_vecs in Cython <-> a numpy array or numpy memoryview?I think it would just be a double for loop or something? This is required to enable pickling, since we need to tell the class how to convert things into a readable Python object, and then also how to go from a readable Python object to low-level Cython code.
We have to decide whether it is easier to convert vector[float] -> numpy array of floats or
float * -> numpy array of floats.
