I've setup a system for supporting multiple implementations for Roblox's
file format. This will allow me to cover the binary format and xml
format under the same general-purpose object.
Haven't done much with the XML format yet, but I've been making some
adjustments to the binary format implementation so that its more evenly
branched out and doesn't retain more information than it needs to. I've
also fixed some issues with the data-types, and documented the Instance
object.
