/**
+ * @class Ext.button.Button
+ * @extends Ext.Component
+
+Create simple buttons with this component. Customisations include {@link #config-iconAlign aligned}
+{@link #config-iconCls icons}, {@link #config-menu dropdown menus}, {@link #config-tooltip tooltips}
+and {@link #config-scale sizing options}. Specify a {@link #config-handler handler} to run code when
+a user clicks the button, or use {@link #config-listeners listeners} for other events such as
+{@link #events-mouseover mouseover}.
+
+{@img Ext.button.Button/Ext.button.Button1.png Ext.button.Button component}
+Example usage:
+
+    Ext.create('Ext.Button', {
+        text: 'Click me',
+        renderTo: Ext.getBody(),        
+        handler: function() {
+            alert('You clicked the button!')
+        }
+    });
+
+The {@link #handler} configuration can also be updated dynamically using the {@link #setHandler} method.
+Example usage:
+
+    Ext.create('Ext.Button', {
+        text    : 'Dyanmic Handler Button',
+        renderTo: Ext.getBody(),
+        handler : function() {
+            //this button will spit out a different number every time you click it.
+            //so firstly we must check if that number is already set:
+            if (this.clickCount) {
+                //looks like the property is already set, so lets just add 1 to that number and alert the user
+                this.clickCount++;
+                alert('You have clicked the button "' + this.clickCount + '" times.\n\nTry clicking it again..');
+            } else {
+                //if the clickCount property is not set, we will set it and alert the user
+                this.clickCount = 1;
+                alert('You just clicked the button for the first time!\n\nTry pressing it again..');
+            }
+        }
+    });
+
+A button within a container:
+
+    Ext.create('Ext.Container', {
+        renderTo: Ext.getBody(),
+        items   : [
+            {
+                xtype: 'button',
+                text : 'My Button'
+            }
+        ]
+    });
+
+A useful option of Button is the {@link #scale} configuration. This configuration has three different options:
+* `'small'`
+* `'medium'`
+* `'large'`
+
+{@img Ext.button.Button/Ext.button.Button2.png Ext.button.Button component}
+Example usage:
+
+    Ext.create('Ext.Button', {
+        renderTo: document.body,
+        text    : 'Click me',
+        scale   : 'large'
+    });
+
+Buttons can also be toggled. To enable this, you simple set the {@link #enableToggle} property to `true`.
+{@img Ext.button.Button/Ext.button.Button3.png Ext.button.Button component}
+Example usage:
+
+    Ext.create('Ext.Button', {
+        renderTo: Ext.getBody(),
+        text: 'Click Me',
+        enableToggle: true
+    });
+
+You can assign a menu to a button by using the {@link #menu} configuration. This standard configuration can either be a reference to a {@link Ext.menu.Menu menu}
+object, a {@link Ext.menu.Menu menu} id or a {@link Ext.menu.Menu menu} config blob. When assigning a menu to a button, an arrow is automatically added to the button.
+You can change the alignment of the arrow using the {@link #arrowAlign} configuration on button.
+{@img Ext.button.Button/Ext.button.Button4.png Ext.button.Button component}
+Example usage:
+
+    Ext.create('Ext.Button', {
+        text      : 'Menu button',
+        renderTo  : Ext.getBody(),        
+        arrowAlign: 'bottom',
+        menu      : [
+            {text: 'Item 1'},
+            {text: 'Item 2'},
+            {text: 'Item 3'},
+            {text: 'Item 4'}
+        ]
+    });
+
+Using listeners, you can easily listen to events fired by any component, using the {@link #listeners} configuration or using the {@link #addListener} method.
+Button has a variety of different listeners:
+* `click`
+* `toggle`
+* `mouseover`
+* `mouseout`
+* `mouseshow`
+* `menuhide`
+* `menutriggerover`
+* `menutriggerout`
+
+Example usage:
+
+    Ext.create('Ext.Button', {
+        text     : 'Button',
+        renderTo : Ext.getBody(),
+        listeners: {
+            click: function() {
+                //this == the button, as we are in the local scope
+                this.setText('I was clicked!');
+            },
+            mouseover: function() {
+                //set a new config which says we moused over, if not already set
+                if (!this.mousedOver) {
+                    this.mousedOver = true;
+                    alert('You moused over a button!\n\nI wont do this again.');
