Bytecode OS

This Readme is separated in two parts:

• The Bytecode part, which shows how to write a binary file and parse it with an executable.

• The OS part, which shows how to create a bare-bone OS that uses the Bytecode part.

If you consider the bare-bone OS as an actual OS, then you could say that the executable from the bytecode part is basically a virtual machine.
