Free data persistence script

Major Features:.

1. Serialization support can often be added to types without modifying those types, or them even being aware they are playing along.
2. Out of the box it supports all STL containers (and work a likes), nested arbitrarily deep.
3. Clients can easily extend it to support their own types using, often non-intrusively.
4. It is data-format agnostic, meaning it doesn't internally care about any file formats. It is container-centric, not stream-centric. The provided i/o layer is just one potential solution to i/o, and the core library can be used with arbitrary client-side i/o mechanisms. The core inherently supports in-memory serialization, not requiring any i/o layer whatsoever (this is useful for serializing over a clipboard-like mechanism and for "casting via serialization").
5. Comes with support for several different file formats, and add-on can be written to provide further formats (e.g., sqlite3 databases).
