Staged NUTS Sampler

The notebook candl_nuts_example.ipynb (located at /OLE/examples/candl/) shows how to run the staged NUTS sampler. In particular, it uses the differentiable CMB likelihood library candl to build a differentiable pipeline, and explores LCDM constraints from SPT-3G 2018 data. This tutorial uses some optional packages. Make sure you have candl (arxiv, github) and getdist (arxiv, github) installed.
