-- CODE language-cs --[Unity C#]
void LoadProject(Int64 projectId, string projectKey, bool autoPlay);

void LoadProject(int64 projectId, FString projectKey, bool autoPlay);

The projectID and projectKey correspond to the values for a project in your PlusMusic account.
If autoPlay is true, the plugin will download and play the first soundtrack in your project. The arrangement used for playback can be set in the global autoPlayArrangement variable (default is backing_track).

On success, LoadProject() will set the global variable theSoundtrackOptions with the values parsed from the PlusMusic web-api json.
