/*------------------------------------------------------------------------------
This add-on cahanges how resources are displayed on the map when using the Map 
Tools. Rsource are shown as 1 or 2 circles with the following characteristics:

Orange Circle:
 - Radius: Represents the total amount of that resource at the planet. For
   minerals this will include ground and surface amounts.
 - Edge Width: For minerals it reresents the density, unless that mineral is
   mined out (5 or less in ground) For other values it represents the expected
   increase in that value (population growth, income, etc.)
Yellow Circle (minerals only):
   Represents the amount of minerals available on the surface. If a planet is
   mined out, this will most likely be the only circle visible.
Natives only:
   When viewing natives a single letter respresenting the native type is
   displayed over the planet. The bigger the letter, the better the
   government.
