Node has a top-level global process object which we should attempt to emulate to some degree. A large amount of it's API is not particularly relevant to us, but for compatibility reasons we should support/expose it and try to implement as much as we can that makes sense.
- process.arch - equivalent to Ti.Platform.architecture
- process.nextTick(callback[, ...args])
- process.platform - Probably equivalent to Ti.Platform.name
- process.version - Equivalent to Ti.version
