Documentation Requests

Please update this list for areas of the World Wind source code that you would like to see documentation for:
 * A good start I think would be to add a 1-line comment to the head of every class describing what it's purpose is
 * I would like a general overview on how terrain gets applied to the Earth, from WW deciding what data to ask for (frustrum/view culling + layer picked) to applying it to the correct tiles, including elevation.
