/**
* Storage driver for fetching authentication data from a PHP Array
*
* This container takes two options when configuring:
*
* cryptType: The crypt used to store the password. Currently recognised
* are: none, md5 and crypt. default: none
* users: A named array of usernames and passwords.
* Ex:
* array(
* 'guest' => '084e0343a0486ff05530df6c705c8bb4', // password guest
* 'georg' => 'fc77dba827fcc88e0243404572c51325' // password georg
* )
*
* Usage Example:
* <?php
* $AuthOptions = array(
* 'users' => array(
* 'guest' => '084e0343a0486ff05530df6c705c8bb4', // password guest
* 'georg' => 'fc77dba827fcc88e0243404572c51325' // password georg
* ),
* 'cryptType'=>'md5',
* );
