Calculate the lengths of many streamlines in a bundle.
Parameters
----------
streamlines : list
Each item in the list is an array with 3D coordinates of a streamline.
affine : 4 x 4 array
An affine transformation to move the fibers by, before computing their
lengths.
Returns
-------
Iterator object which then computes the length of each
streamline in the bundle, upon iteration.
