Transformer logger use

Thanks for flagging this @m4olivei. We could consider implementing a custom renderer, but I think just concatenating the message with newlines as you suggest is probably a simpler and better approach. We'll look into it.

Im considering to have a better log on the Transformation process.
Like we have today "warnings" stored under the Transformer object, we can have the step-by-step log there, and we can flush it as we finish to process the file.

Something like:

    // processing and transforming code
    $transformer->appendLog($message)

    // after transformation ends
    $logger->debug($transformer->getFormattedLog());

PR #304 for this.
