How to use yarp logging in Python applications?

[ddetommaso]

I would like to exploit yarp logging in Python applications but I am encountering a few errors using the bindings.
I am listing below some of the issues I have found and the relative question.

1. How to properly instantiate Yarp.Log ?
   At the moment instantiating the yarp.Log() without parameters causes seg fault. As workaround I need to define something like yarp.Log("",0,"")

2. How to use components and id ?
   Recently the logging methods include the possibility to define components and ids. It would be helpful to exploit this feature for Python apps as well. At the moment the bindings not include the LogComponent class, but even including the import in yarp.i defining a yarp.LoComponent("mycomponent") does not work as expected. Is there a workaround to make components and/or ids work?

3. How to filter out all the yarp loggings in the console output when executing a Python app using yarp?
   I have tried with YARP_QUIET but still I get some of the logging from devices during initialization.

Many thanks
