- `NotEmpty()`

Validates wether the given input is not empty. This function also takes whitespace

whitespace anywhere in the input is desired.

```

Null values are empty:

```php
v::notEmpty()->isValid(null); // false
```

Numbers:

```php
v::intVal()->notEmpty()->isValid(0); // false
```

Empty arrays:

```php
v::arrayVal()->notEmpty()->isValid([]); // false
```

Whitespace:

```php
v::stringType()->notEmpty()->isValid('        ');  //false
v::stringType()->notEmpty()->isValid("\t \n \r");  //false
```
