/**
*
* Raw erasure coders.
*
* Raw erasure coder is part of erasure codec framework, where erasure coder is
* used to encode/decode a group of blocks (BlockGroup) according to the codec
* specific BlockGroup layout and logic. An erasure coder extracts chunks of
* data from the blocks and can employ various low level raw erasure coders to
* perform encoding/decoding against the chunks.
*
* To distinguish from erasure coder, here raw erasure coder is used to mean the
* low level constructs, since it only takes care of the math calculation with
* a group of byte buffers.
