Transport class is not documented

[ozydingo]

The feature you'd like

On Tone.js's API documentation page, the TransportClass (returned by Tone.getTransport, which is documented), does not seem to be documented. Older versions of the docs found via google do have this class documented. Can the documentation for v 15 be updated to include this class?

Any alternatives you've considered
