Integrate Timber with some other logging implementation

[andyrozman]

So I am working on OS project and we have our own logging that is used through whole application. Now we started using one library that uses Timber for logging. So far we see no logging messages from that library in our logs.
We need to find a way to redirect all log messages from Timber into our logging solution (we need to see all logs in single file). Is there easy way to do this?

Implement the Tree interface that sends calls to wherever you want. Call Timber.plant(Tree) with an instance of it.
