"""Wrapping an array-like object (typically an on-disk object) in a
DelayedArray object allows one to perform common array operations on it
without loading the object in memory. In order to reduce memory usage
and optimize performance, operations on the object are either delayed
or executed using a block processing mechanism. Note that this also
works on in-memory array-like objects like DataFrame objects (typically
with Rle columns), Matrix objects, and ordinary arrays and data frames.
