Feature Request: metal-mask component

[stiemannkj1]

I need a mask component which can limit inputs to certain values while a user is entering them. For example, it would be useful to limit an input to only accept an American phone number or an American style date. Masking is similar to validation, but it should actually be able to prevent a user from putting letters into a phone number etc. It should also be able to show the format of the input before it is entered. The client-side part of p:inputMask (which uses a jQuery masked input plugin) is a good example of the feature I am looking for.
