Remarks

ClearLayers removes all layers types from the Map.  ClearLayers does not change or reset the Map's spatail reference however.  In addition, ClearLayers does not affect any graphics stored in the Map's BasicGaphicsLayer - it's not a true Layer.  ClearLayers does not update the contents view (TOC) or the display.
