Expand description

This is how to use the Forth tokenizer library

use rust_forth_tokenizer::ForthToken;
use rust_forth_tokenizer::ForthTokenizer;

    let tokenizer = ForthTokenizer::new("word : wordname 1 2 3 ; definition");
    // The code also supports the regular for loop iterator syntax
    let collected: Vec<_> = tokenizer.into_iter().collect();
    assert_eq!(
           &collected,
           &vec![
               ForthToken::Command("word"),
               ForthToken::Colon,
               ForthToken::Command("wordname"),
               ForthToken::Number(1),
               ForthToken::Number(2),
               ForthToken::Number(3),
               ForthToken::SemiColon,
               ForthToken::Command("definition"),
           ]
       );

This Enum lists the token types that are used by the Forth interpreter
