/**
 * MaskedInput generates a masked text input.
 *
 * MaskedInput is similar to [[Html::textInput()]] except that
 * an input mask will be used to force users to enter properly formatted data,
 * such as phone numbers, social security numbers.
 *
 * To use MaskedInput, you must set the [[mask]] property. The following example
 * shows how to use MaskedInput to collect phone numbers:
 *
 * ~~~
 * echo MaskedInput::widget([
 *     'name' => 'phone',
 *     'mask' => '999-999-9999',
 * ]);
 * ~~~
 *
 * The masked text field is implemented based on the [jQuery masked input plugin](http://digitalbush.com/projects/masked-input-plugin).
