// XDialog implementation has the following interesting bits
// a Controls property ( which is an array of the container controls )
//   each item in the controls array is a XControl, where the model is
//   basically a property bag
// additionally the XDialog instance has itself a model
//     this model has a ControlModels ( array of models ) property
//     the models in ControlModels can be accessed by name
// also the XDialog is a XControl ( to access the model above
