| /// is defined as any logical unit of data which may be arranged inside the MSF |
| /// file as a sequence of (possibly discontiguous) blocks. When we want to read |
| /// from a particular MSF Stream, we fill out a stream layout structure and the |
| /// reader uses it to determine which blocks in the underlying MSF file contain |
| /// the data, so that it can be pieced together in the right order. |
