  Settings Explaination:
  1. writeObjID - the html element id to which the map will be written
  2. startCoords - the centerpoint of the map
  3. startPin - default centerpoint pin, also has a directions to/from option
  4. mapStyle - choose between "a","r","h", and "o"
  5. zoom - starting zoom level
  6. miniMap - a minimap, contains starting settings, that uses css to position itself
  7. miniMapIDClasses - the css associated with the minimap
  8. returnFunc - callback function - can return 2 parameters:
        a. the map object
        b. null, unless a georss feed is used, then returns array of objects
           for each of the georss entries containing:
            1.title
            2.id (the id used by virtual earth to identify a shape)
            3.latitude
            4.longitude
            5.description
  9.pins - an array of objects for additional pins
        a. latitude
        b. longitude
        c. maxZoom
        d. minZoom
        e. title
        f. description
        g. icon (the file path)
        h. directions (get directions from/to a point)
  10.tiles - an array of objects for tile layers (overlays)
        a. id
        b. path
        c. maxZoom
        d. minZoom
        e. zIndex (css addition, sometimes the tiles are interfered with)
  11.geoRss - a georss feed option, the directions option turns directions on for points
  12.cluster - uses the default virtual earth clustering algorithm
