I have attempted to use "using QuantConnect.Lean.Engine.Results" in an attempt to access the backtest result statistics from an algorithm; however, I get the error that "the namespace 'Lean' does not exist in the namespace 'QuantConnect.'" I'm not sure why this is since the documentation on github shows similar use of the namespace in other classes? I'd like to display my custom statistics in the IDE results and/or print to the console or csv. Any help here would be greatly appreciated, thank you!
