Create shop by chests. No config needed!
No other people other than the shop owner can break the chest!
To create shop, you just have to write the following on a sign that is attached onto a chest!
```
[Shop]
<Item count> <coin item>
```
Example:
```
[Shop]
10 diamond_block
```
This will create a shop that sells stuff inside the chest witn 10 diamond blocks!
