corrected docstring of new_vec method: it returns a column vector.

[Mickanos]

The implementation of the new_vec method for the Matrix struct seems to return a column vector:

    pub fn new_vec(data: Vec<F::Element>, field: F) -> Matrix<F> {
        Matrix {
            nrows: data.len() as u32,
            ncols: 1,
            data,
            field,
        }
    }

However, the original docstring states that the method returns a row vector:

/// Create a new row vector from a list of scalars.

The docstring is therefore updated to

/// Create a new column vector from a list of scalars.

Thanks! Can you also make the same change in python.rs and symbolica.py?
