Model

In Docupace Start UI for the widget, the model is created to store the state of all fields and field groups on the page.

You can access the widget model using `$scope.widgetAppModel`
The model is available in the field execution context as `model`.
For input fields, wherein user enters data (Text input, Single select, Field group, etc.) `model` refers to the model of this field.
For other field types, that do not receive data from the user (Rich-text, Separator, Action (button), Image, etc.) `model` refers to the model of the containing Field group.
