/**
* Generate a buffer by rendering all of the Tone.js code within the callback using the OfflineAudioContext.
* The OfflineAudioContext is capable of rendering much faster than real time in many cases.
* The callback function also passes in an offline instance of Tone.Transport which can be used
* to schedule events along the Transport. **NOTE** OfflineAudioContext has the same restrictions
* as the AudioContext in that on certain platforms (like iOS) it must be invoked by an explicit
* user action like a click or tap.
* @param {Function} callback All Tone.js nodes which are created and scheduled within this callback are recorded into the output Buffer.
* @param {Time} duration the amount of time to record for.
* @return {Promise} The promise which is invoked with the Tone.Buffer of the recorded output.
* @example
* //render 2 seconds of the oscillator
* Tone.Offline(function(){
* //only nodes created in this callback will be recorded
* var oscillator = new Tone.Oscillator().toMaster().start(0)
* //schedule their events
* }, 2).then(function(buffer){
* //do something with the output buffer
* })
* @example
* //can also schedule events along the Transport
* //using the passed in Offline Transport
* Tone.Offline(function(Transport){
* var osc = new Tone.Oscillator().toMaster()
* Transport.schedule(function(time){
* osc.start(time).stop(time + 0.1)
* }, 1)
* Transport.start(0.2)
* }, 4).then(function(buffer){
* //do something with the output buffer
* })
