Create add user wrapper function

Take this:

user_save(new stdClass(),
  array('name' => 'wbrtech',
 'pass' => 'music123#',
 'mail' => 'tech@warnerreprise.com',
 'status' => 1));

And turn it into a wrapper function. Pass in name, mail, pwd (optional), status (optional). Should probably return the ID# of the user.
