Detailed Description

A BlobLite holds a pointer to an immutable pre-allocated buffer and its length This is like a JavaScript string which is a pointer to an immutable string.

It is OK to pass a pointer to the string because the new owner can't change the bytes of the string. However, like a JavaScript string, it is possible to change the pointer, and so this does allow the copy constructor and assignment to change the pointer. Also remember that the pointer can be null.
