seax 0.0.2

SECD virtual machine for interpreting programs in FP languages and a Scheme compiler targeting that machine.
## What's going on here?

Seax is a VM for interpreting Lisp programs.

## Goals

+ A complete implementation of a simple Lisp
    * Probably Scheme
    * like Scheme, it's minimal, elegant, & still expressive
+ Modular/general purpose enough to interpret other languages 
    * there should be a modular API for front ends
+ Performant enough to support "Real Programs"
    * Speed should be at least as good as Python

## Stretch goals

These are things that I would like to add, if there's time, but I may not be able to add all of them.

+ Foreign function interface
    * so that you can make Real Software and I don't have to write a whole standard library
    * probably into the C stdlib 'cause it's everwhere
    * this will require some additional research
+ some kind of JIT compilation
    * I don't know how feasible this is
    * this will require additional research as well
+ Additional language frontends
    * one or more
    * this can include "toy languages" that are interesting but not really useful
    * the goal is to demonstrate that the SECD architecture is capable of interpreting multiple programming languages

## Why Rust?

I'm using the Rust programming language. Here's why:

+ It's intended for systems programming
    * reasonably good performance (not C but pretty close)
        - compiled
        - interesting approach to memory management (eliminates a lot of GC)
    * access to low-level stuff
+ But it's not C
    * modern syntax
    * nice build system (Cargo)
+ I've wanted to learn it for a while
