{Array(OpenLayers.Control)}
{OpenLayers.Control} The control which is activated when the control is activated (turned on), which also happens at instantiation. If saveState is true, defaultControl will be nullified after the first activation of the panel.
Create a new control panel.
Each control in the panel is represented by an icon. When clicking on an icon, the activateControl method is called.
| type | {Number} One of OpenLayers.Control.TYPE_TOOL, OpenLayers.Control.TYPE_TOGGLE, OpenLayers.Control.TYPE_BUTTON. If not provided, OpenLayers.Control.TYPE_TOOL is assumed. |
| title | {string} Text displayed when mouse is over the icon that represents the control. |
The OpenLayers.Control.type of a control determines the behavior when clicking its icon: OpenLayers.Control.TYPE_TOOL - The control is activated and other controls of this type in the same panel are deactivated. This is the default type. OpenLayers.Control.TYPE_TOGGLE - The active state of the control is toggled. OpenLayers.Control.TYPE_BUTTON - The OpenLayers.Control.Button.trigger method of the control is called, but its active state is not changed.
If a control is OpenLayers.Control.active, it will be drawn with the olControl[Name]ItemActive class, otherwise with the olControl[Name]ItemInactive class.
| options | {Object} An optional object whose properties will be used to extend the control. |

getControlsBy: function( property, match )
Get a list of controls with properties matching the given criteria.
| property | {String} A control property to be matched. |
| match | {String | Object} A string to match. Can also be a regular expression literal or object. In addition, it can be any object with a method named test.
