CMaskedTextField generates a masked text field.
CMaskedTextField is similar to CHtml::textField except that an input mask will be used to help users enter properly formatted data. The masked text field is implemented based on the jQuery masked input plugin (see http://digitalbush.com/projects/masked-input-plugin).
