fixing bug introduced with [179]. basically, the Layer constructor should not be making new divs when it is initialized by a subclass. that was the point of [179]. the problem is that because of the way Layer.Grid is making the call to Layer's initialize() -- createing a new arguments array regardless of the orginal (ie although name is void, it nonetheless creates a new array with one element, a void element) well so then when init gets called it thinks it does have arguments. The real god's truth here is that we need a better way than if (arguments.length > 0) to distinguish between actual object creation and the creation of the classes.
