Reset becoming a function also?

Hi,

I'm currently using reset as follows as
```
this.$refs.infiniteLoading.$emit('$InfiniteLoading:reset');
```

Is there plans to create a `reset()` function or exposing the `$state` when I use `$refs` making one of the following 2 possible
```
this.$refs.infiniteLoading.reset();
this.$refs.infiniteLoading.$state().reset();
```
