[jQuery] mask input plugin - meioMask

Hi all, i want to present a jQuery plugin that masks text inputs on a
form.
It will mask the input while you are entering the input you want,
helping the users to write exactly what the developer wants.
See the docs for more details and a better understanding:

And comment at my blog here:

Cheers.
