Basic infrastructure for taking a list of parameters from a plugin and turning it into a collection of UI controls, merging in values from a Visualization object. Doesn't yet do anything useful. WPF makes the hard things easy and the easy things hard. This was a hard thing, so it was easy to do (with some helpful sample code). Yay WPF?
