r⁷rs scheme implemetation in zig.

Current status:

• r7rs lexer based on section 7.1.1 of r7rs spec
• parser with exception of (a . b) and (a b c d . e) expressions (need to test .)
• addition of integers in a tree-walk-interpreter.

TODO

This section is incomplete and just of list of things to implement in roughly the order I expect to implement them in.

• Lexer
  • Nested Comments
  • Tests
    • Preliminary unit tests done. Need to write tests for Lexer.getNextToken.
  • Simplification?
• Parser
  • Cons and improper lists
    • Should be done, but need to test.
  • Tests
• Tree-Walk-Interpreter
  • Addition of integers
  • Simple Expressions
  • Big-Ints
  • Garbage Collector
  • Lambdas
  • Syntax-rules
  • r7rs records
  • r7rs libraries
• Bytecode Interpreter
• Native compiler?
