/**
 * @class Ext.QuickTips
 * <p>Provides attractive and customizable tooltips for any element. The QuickTips
 * singleton is used to configure and manage tooltips globally for multiple elements
 * in a generic manner.  To create individual tooltips with maximum customizability,
 * you should consider either {@link Ext.Tip} or {@link Ext.ToolTip}.</p>
 * <p>Quicktips can be configured via tag attributes directly in markup, or by
 * registering quick tips programmatically via the {@link #register} method.</p>
 * <p>The singleton's instance of {@link Ext.QuickTip} is available via
 * {@link #getQuickTip}, and supports all the methods, and all the all the
 * configuration properties of Ext.QuickTip. These settings will apply to all
 * tooltips shown by the singleton.</p>
 * <p>Below is the summary of the configuration properties which can be used.
 * For detailed descriptions see {@link #getQuickTip}</p>
 * <p><b>QuickTips singleton configs (all are optional)</b></p>
 * <div class="mdetail-params"><ul><li>dismissDelay</li>
 * <li>hideDelay</li>
 * <li>maxWidth</li>
 * <li>minWidth</li>
 * <li>showDelay</li>
 * <li>trackMouse</li></ul></div>
 * <p><b>Target element configs (optional unless otherwise noted)</b></p>
 * <div class="mdetail-params"><ul><li>autoHide</li>
 * <li>cls</li>
 * <li>dismissDelay (overrides singleton value)</li>
 * <li>target (required)</li>
 * <li>text (required)</li>
 * <li>title</li>
 * <li>width</li></ul></div>
 * <p>Here is an example showing how some of these config options could be used:</p>
 * <pre><code>
// Init the singleton.  Any tag-based quick tips will start working.
Ext.QuickTips.init();

// Apply a set of config properties to the singleton
Ext.apply(Ext.QuickTips.getQuickTip(), {
    maxWidth: 200,
    minWidth: 100,
    showDelay: 50,
    trackMouse: true
});

// Manually register a quick tip for a specific element
Ext.QuickTips.register({
    target: 'my-div',
    title: 'My Tooltip',
    text: 'This tooltip was added in code',
    width: 100,
    dismissDelay: 20
});
</code></pre>
 * <p>To register a quick tip in markup, you simply add one or more of the valid QuickTip attributes prefixed with
 * the <b>ext:</b> namespace.  The HTML element itself is automatically set as the quick tip target. Here is the summary
 * of supported attributes (optional unless otherwise noted):</p>
 * <ul><li><b>hide</b>: Specifying "user" is equivalent to setting autoHide = false.  Any other value will be the
 * same as autoHide = true.</li>
 * <li><b>qclass</b>: A CSS class to be applied to the quick tip (equivalent to the 'cls' target element config).</li>
 * <li><b>qtip (required)</b>: The quick tip text (equivalent to the 'text' target element config).</li>
 * <li><b>qtitle</b>: The quick tip title (equivalent to the 'title' target element config).</li>
 * <li><b>qwidth</b>: The quick tip width (equivalent to the 'width' target element config).</li></ul>
 * <p>Here is an example of configuring an HTML element to display a tooltip from markup:</p>
 * <pre><code>
// Add a quick tip to an HTML button
&lt;input type="button" value="OK" ext:qtitle="OK Button" ext:qwidth="100"
     ext:qtip="This is a quick tip from markup!">&lt;/input>
</code></pre>
