Specify the geometric distribution in tutorial
Just specifying which geometric distribution we refer to avoid confusion for the reader.

- "Because Pyro is embedded in Python, stochastic functions can contain arbitrarily complex deterministic Python and randomness can freely affect control flow. For example, we can construct recursive functions that terminate their recursion nondeterministically, provided we take care to pass `pyro.sample` unique sample names whenever it's called. For example we can define a geometric distribution like so:"
