not found: type InitializedLenser

I want to use the dynamic lenser (because that's inside a generic class, so the static one doesn't work). I tried both 0.1.0 and 0.2.0, but I only get the following error when trying to do anything:

```
case class Foo(name: String)
val lf = rillit.dynamic.Lenser[Foo]()
lf.name.get
```

The error in the last line:

```
not found: type InitializedLenser
```
