[Clam-devel] Patch with questions: tooltip on ProcessingTree

[David García Garzón]

Notice that last commits on NetEditor are moving CLAM dependant features out 
of the ProcessingBox and even out of NetworkCanvas because we want to reuse 
the NetworkCanvas for other kind of networks: currently Jack networks in the 
new NetEditor tab, but also enabling it for reuse in other projects. 

So any of the CLAM dependant code (ie, looking up in the factory metadata) 
should be delegated to a virtual function in the canvas (which name should 
have a 'generic' meaning) and implement it on the concrete method of 
ClamNetworkCanvas.

Also, be aware that you are using the name as key for the factory. This works 
because name and type match when you drop one processing into the canvas, but 
the second one will be named Oscillator_2 instead just Oscillator.
