rigz_runtime

Handles parsing and converting rigz to its VM instructions.

Parser

This is an AST parser, but as soon as it has an element that would be in the AST that element is converted into VM instructions. Tokens and expressions are read from left to right, there is no operator precedence. This means that 1 + 2 * 3 is not equal to 3 * 2 + 1; the first is 9, (1 + 2) * 3, while the second is 7, (3 * 2) + 1.

TODO

• update parser to support repl, may require VM updates as well

• Better error messages

## todo
- support multiple parsers
    - default ignore precedence; 1 + 2 * 3 = 9
    - right recursive precedence; 1 + 2 * 3 = 7
    - pratt parser; 1 + 2 * 3 / 4 = 2.5
