/**
 *
 * Mobile devices are detected with
 * {@link http://code.google.com/p/php-mobile-detect/ php-mobile-detect}.
 * A particular theme may be designated for <i>phones</i> and for <i>tablets</i>. If the connecting
 * device is one of those, the theme will automatically switch to the designated mobile theme.
 *
 * Test mode allows you to run your standard desktop client but simulate being either a <i>phone</i> or
 * a <i>tablet</i>.
 *
 * You may place a call on <var>mobileTheme::controlLink();</var> in your theme(s) to allow the client viewer
 * to override the switch and view your standard gallery theme. If the same call is placed in your gallery
 * theme he will be able to switch back as well.
 * <b>NOTE:</b> This link is present only when the browsing client
 * is a mobile device!
 *
 * Class <var>mobile</var> methods you can use in your theme:
 * <ul>
 * 	<li>phone is connected.
 * 	<ul>
 * 		<li>isiPhone()</li>
 * 		<li>isBlackBerry()</li>
