In NestedWindowWorld, WindowBuilders
build nested window patterns. We can specify the size of the
initial window (ie the length of one side -- all windows are squares)
and the number of levels of nesting. When we create a
WindowBuilder wanda, she starts at a specific
place with her pen down and facing the right. If we ask her to build
a window with fewer than one level of nesting, she does nothing. She
builds a one level window pattern with the bottom left corner of the
window at her starting position. Regardless of the number of levels
of nesting in the window pattern she builds, wanda stands in
her initial position facing her initial direction when she is
finished. The following pictures illustrate the result from asking
wanda to build windows patterns with different levels of
nesting.

Our task is to fill in the code for the
buildDiagonallyNestedWindows method in the
WindowBuilder class. The following skeleton is provided
for us.
public void buildDiagonallyNestedWindows (double size, int levels) {
System.out.println("buildDiagonallyNestedWindows("+size+", "+levels+");");
// add your code here
}
We may also want to define auxiliary methods in the
WindowBuilder class. We should not need to modify the
NestedWindowWorld class in order for our code to work.
However, we may modify it during testing.
