size how big to make the sequence.

orphan if the next batch would contain less items than this

overlap the number of items shared between adjacent batches

Attributes: Note that the "start" attribute, unlike the
argument, is a 1-based index (I know, lame). "first" is the
0-based index. "length" is the actual number of elements in
the batch.
"sequence_length" is the length of the original, unbatched, sequence.
