Conversation
Allow images to be put into an array of objects, but not array of scalar types This prevents obscure errors when an operation is meant to operate on img.numpy() but is passed img instead.

Allow images to be put into an array of objects, but not array of scalar types
This prevents obscure errors when an operation is meant to operate on img.numpy() but is passed img instead.
Fixes #863, but might break some code putting antsImage objects into numpy object arrays. These now need explicit type, eg
np.asarray([img1, img2])
no longer works, but
np.asarray([img1,img2], dtype='object') does work.
