function example_required_callback in Required by role 7

Example callback for hook_required_by_role_callback_alter.

This callcack is intended to the actual work on working whether or not the #required property of a field is TRUE or FALSE

The callback takes as arguments, the account to be used (by default the current user), the roles to matched against, the context provided by hook_field_widget_form_alter and the $form_state

This is an example on how to alter the account that is going to be tested based on the form_id. Sometime would be useful to use $context to get extra information about the environment.
