Hello,

I’m trying to learn Turing.jl and the concepts behind it and I’m not seeing any documentation that explains what the parameters are that are passed to `NUTS()`

when sampling. The documentation utilizes the NUTS sampler in several of the tutorials but I can’t seem to find anything that explains what the function arguments are. For example, when using the NUTS sampler with a linear regression model:

```
chain = sample(model, NUTS(200, 0.65), 1500)
```

What are 200, 0.65 and 1500?
