Moving around a star map

Going with a 10 LY cube, this time. The page will fill a 10 by 10 by 10 grid of LY^3 with stars based on a PR# generated from the coordinates of that LY^3. There should be an average of about 43 star systems or points of interest (I'll need to figure that out!).
Movement around the map will involve clicking on the star div. As each star system is generated the page makes a clickable daughter div and places it within the parent star map div. Selecting a star causes the page to erase the current map and generate a new grid centered on the selected coordinates.
