Digital camera raw format library

Rawler parses raw file formats and provides access to the pixels and all metadata.

It's a (c)rawler, just for raw file structures.

• There are libraries dealing with metadata (exiv2) and for pixels (rawspeed, libraw), but not for both. Each library ships their own file structure parsers.
• rawloader, which is basically the fundament of this library, is a pretty good library, but lacks of support for metadata.
• For fun.
