/**
 * @class Ext.tip.QuickTipManager
 *
 * 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.Tip} or {@link Ext.tip.ToolTip}.
 *
 * Quicktips can be configured via tag attributes directly in markup, or by
 * registering quick tips programmatically via the {@link #register} method.
 *
 * The singleton's instance of {@link Ext.tip.QuickTip} is available via
 * {@link #getQuickTip}, and supports all the methods, and all the all the
 * configuration properties of Ext.tip.QuickTip. These settings will apply to all
 * tooltips shown by the singleton.
 *
 * Below is the summary of the configuration properties which can be used.
 * For detailed descriptions see the config options for the {@link Ext.tip.QuickTip QuickTip} class
 *
 * ## QuickTips singleton configs (all are optional)
 *
 *  - `dismissDelay`
 *  - `hideDelay`
 *  - `maxWidth`
 *  - `minWidth`
 *  - `showDelay`
 *  - `trackMouse`
 *
 * ## Target element configs (optional unless otherwise noted)
 *
 *  - `autoHide`
 *  - `cls`
 *  - `dismissDelay` (overrides singleton value)
 *  - `target` (required)
 *  - `text` (required)
 *  - `title`
 *  - `width`
 *
 * Here is an example showing how some of these config options could be used:
 *
 * {@img Ext.tip.QuickTipManager/Ext.tip.QuickTipManager.png Ext.tip.QuickTipManager component}
 *
 * ## Code
 *
 *     // Init the singleton.  Any tag-based quick tips will start working.
 *     Ext.tip.QuickTipManager.init();
 *    
 *     // Apply a set of config properties to the singleton
 *     Ext.apply(Ext.tip.QuickTipManager.getQuickTip(), {
 *         maxWidth: 200,
 *         minWidth: 100,
 *         showDelay: 50      // Show 50ms after entering target
 *     });
 *    
 *     // Create a small panel to add a quick tip to
 *     Ext.create('Ext.container.Container', {
 *         id: 'quickTipContainer',
 *         width: 200,
 *         height: 150,
 *         style: {
 *             backgroundColor:'#000000'
 *         },
 *         renderTo: Ext.getBody()
 *     });
 *    
 *    
 *     // Manually register a quick tip for a specific element
 *     Ext.tip.QuickTipManager.register({
 *         target: 'quickTipContainer',
 *         title: 'My Tooltip',
 *         text: 'This tooltip was added in code',
 *         width: 100,
 *         dismissDelay: 10000 // Hide after 10 seconds hover
 *     });
 *
 * To register a quick tip in markup, you simply add one or more of the valid QuickTip attributes prefixed with
 * the **ext** namespace.  The HTML element itself is automatically set as the quick tip target. Here is the summary
 * of supported attributes (optional unless otherwise noted):
 *
 *  - `hide`: Specifying "user" is equivalent to setting autoHide = false.  Any other value will be the same as autoHide = true.
 *  - `qclass`: A CSS class to be applied to the quick tip (equivalent to the 'cls' target element config).
 *  - `qtip (required)`: The quick tip text (equivalent to the 'text' target element config).
 *  - `qtitle`: The quick tip title (equivalent to the 'title' target element config).
 *  - `qwidth`: The quick tip width (equivalent to the 'width' target element config).
 *
 * Here is an example of configuring an HTML element to display a tooltip from markup:
 *    
 *     // Add a quick tip to an HTML button
 *     <input type="button" value="OK" ext:qtitle="OK Button" ext:qwidth="100"
 *          data-qtip="This is a quick tip from markup!"></input>
 *
