-* set the default message handler i.e. function which take the incomming message as argument and return a stringable value to give back to Pure-Data
-* with message handler registration system you can use different function depending of the first word of the incomming message. Simply call `PureDataServer.register_message_handler([first_word], function_to_call)`

 Pure-Data messages are text only so the FreeCAD objects have to be converted to and from string to be processed with Pure-Data.
 
-The PureDataServer object automaticaly remove non-conform characters of the callback message i.e. `,` and `=` are converted to space and `';()\[\]{}"` are removed. In this way the `Base.Vector` python object whose string representation is `Vector(0.0,0.0,0.0)` can be a return value of a message handler and converted to `Vector 0.0 0.0 0.0` PD message.
