G-Machine

Implement Chapter 3, Marks 1-6. Driver is updated to switch between G-Machine and TI Machine.

Template Instantiation Machine

Implement Chapter 2 of the TI machine, Marks 1-5. Exceptions:

• The Print/Stop primitives described at the end of Mark 5.
• The alternative implementations described after Mark 5, such as the garbage collector.
• case statements are not implemented, because of the difficulties stated in the book (see: this Stack Overflow post)
• Lambda abstractions are not implemented since they are introduced in Chapter 6

Also implement a basic driver with command-line options.
