// description:
// Moves the mouse over the specified node at the specified relative x,y offset.

// The id of the node, or the node itself, to move the mouse to.

// This is useful if you need to move the mouse to an node that is not yet present.

// delay:
// Delay, in milliseconds, to wait before firing.
// The delay is a delta with respect to the previous automation call.
// For example, the following code ends after 600ms:
// doh.robot.mouseClick({left:true}, 100) // first call; wait 100ms
// doh.robot.typeKeys("dij", 500) // 500ms AFTER previous call; 600ms in all

// Approximate time Robot will spend moving the mouse
// The default is 100ms.

// x offset relative to the node, in pixels, to move the mouse. The default is half the node's width.

// offsetY:
// y offset relative to the node, in pixels, to move the mouse. The default is half the node's height.
