This crate provides functions for converting EOSIO names and symbols, represented as u64, to and from string representations.

Converting names:

```rust use eosionumstr::{namefromstr, nameto_string};

let name = namefromstr("eosio").unwrap(); asserteq!(name, 6138663577826885632); asserteq!(nametostring(name), "eosio"); ```

Converting symbols:

```rust use eosionumstr::{symbolfromstr, symbolto_string};

let symbol = symbolfromstr(4, "EOS").unwrap(); asserteq!(symbol, 1397703940); asserteq!(symboltostring(symbol), "EOS"); ```
