PureDataWrapper class is operative but needs a complete rewrite.
Specifically, it should run in its own thread instead of using 
asynchronous i/o and the awful yield calls. This will also allow 
to make it independent from wx libs.

Currently audio configuration should be performed using pd interface,
thus a full configuration dialogue will be highly desirable.

On linux several pd externals such as OSCx and prepend are not
provided by most distributions, so currently the configuration dialogue
and playing with the voice activity do not work. Consider building
these externals as part of the project.

It will be highly desirable to export an existing pd patch (specially 
tweaked) as an component with its own input and output pins.
