IPreprocessor class abstract

Some form fields might require an initial data that is used in a value preparation, e.g. a LitePhoneInputField might require country data, phone code etc. It utilizes a custom IPreprocessor to set all that data before changing a value The preprocessor is connected to its field and does not depend on a widget's state

See an example in LitePhoneInputField
