Detailed Description

blob is the general representation of a "block" of information. . 'data' must be exactly 'length' bytes and must be entirely self contained. It must not hold references to other memory regions. That is to say, I should be able read off exactly 'length' bytes from 'data', and send it across a network/write it to a disk/etc, and the information should still be consistent The blob is self-managed and will free and delete the underlying memory when it goes out of scope.
