It differs from Input in a few ways:

1. It expects the raw value to be in the $_FILES array format.

2. The validators are run before the filters (the opposite behavior of Input). This is so is_uploaded_file() validation can be run prior to any filters that may rename/move/modify the file.

3. Instead of adding a NotEmpty validator, it will (by default) automatically add a Zend\Validator\File\Upload validator.
