/**
 * @class Ext.QuickTips
 * 
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}.
 * 
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.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.
 * 
Below is the summary of the configuration properties which can be used.
 * For detailed descriptions see {@link #getQuickTip}
 * 
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:
 * 

// 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
});

 * 
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"
     ext:qtip="This is a quick tip from markup!"></input>
