Support for Volocity format

There are several file types involved in the Volocity database structure, including .mvd2, .acff, .atsf, .aiix, .aisf, .dat, and possibly others. There is also a Volocity flavor of TIFF, with plain-text metadata in the header, that we should verify is parsed and converted correctly. See the readmes in data/volocity for more details.

Additional comment from (duplicate) ticket #3:

Several people, including Michael Schell, Jeremy Sanderson, Kurt De Vos and Johannes Schindelin, would benefit from direct support for Volocity's database format; Jeremy sent .acff files; Mike sent .mvd2 (Multi-file Library version 2), .atsf, .aiix, .aisf and .dat.

The .mvd2 files are Metakit databases (, and pixels appear to be stored raw, with one file per channel per dataset.

Thus, there are two basic steps to implementing support for this format. The first is to come up with a way to read Metakit db's in Java, either by writing a wrapper for the existing C++ library or by writing a native Java library based on the file format documentation. The second step is to use the Metakit library to read the .mvd2 files, which (hopefully) contain linkages to the pixels/metadata files. The Metakit library should probably be a standalone library (i.e. not in loci.formats).
