> tree.loss.Losses.fromString expects certain String names for losses.  These do not match the names of the loss classes but should.  I believe these strings were the original names of the losses, and we forgot to correct the strings when we renamed the losses.
> Currently:
> {code}
>     case "leastSquaresError" => SquaredError
>     case "leastAbsoluteError" => AbsoluteError
>     case "logLoss" => LogLoss
> {code}
> Proposed:
> {code}
>     case "SquaredError" => SquaredError
>     case "AbsoluteError" => AbsoluteError
>     case "LogLoss" => LogLoss
> {code}
