dicer 0.2.0

# Dicer
version 0.2.0

## About
A simple library for evaluating strings representing dice rolls in rust. Dicer uses an _LL(1)_ grammar and a recursive descent parser to parse strings and
simulate randomly rolled dice. See [grammar.md](https://github.com/gnullByte/dicer/blob/main/grammar.md) for examples of valid strings.

## Example
```rust
use dicer::eval;

fn main() {
    let test = String::from("1d20 * (3+2) + min([2d4 - MAX], 3)");

    println!("parse: \"{}\"\n", test);
    let result = eval(&test).expect("uh oh");
    println!("{}", result.value);
    println!("{}", result.str);
}
```

output:
```
parse: "1d20 * (3+2) + min([2d4 - MAX], 3)"

31
(6) * (3 + 2) + min([ (3 + 1) -3 ], 3)
```
