TODO: Add Import directory and project

Description:

We need an app that can take one or more imported projects that have wxPanel as a form and where the original designer has generated code. That allows wxUiEditor to import the project, generate its own code and then the app could be built with a dialog that has both panels side by side for UI comparison. This needs to be flexible enough that it is relatively straightforward to add multiple panels from multiple designers.

It would probably also make sense to add comparison for wxPython as well since both wxFormBuilder and wxGlade generate wxPython code.
