Get a sub-schema of an existing schema based on a `path` that can be either a string or an array of strings For string values path separator is a dot (`.`).

```js
const schema = Joi.object({ foo: Joi.object({ bar: Joi.number() }) });
const number = Joi.reach(schema, 'foo.bar');

//or
const result = Joi.reach(schema, ['foo', 'bar']); //same as number
```
