Inode Schema

{"camliVersion": 1,
 "camliType": "inode",
 "inodeId": 12345  // st_ino
 "deviceId": 53,   // st_dev
 "numLinks": 3,    // st_nlink
}

This is optional and probably rarely used, but lets two+ files be represented as hardlinks with each other. If both files point to the same inode object, they're hardlinks of each other.

Note that unlink "directory", "file", and "schema", this does not inherit fields from the "file-common" schema.
