-/// \mainpage gtl -- Geometry Template Library
-/// The geometry template library is a Concepts based typesystem that implements that API and algorithms for a large number of planar (2D) geometry operations.  The primary algorithms provided by gtl are polygon set operations, so-called Booleans, such as polygon intersection and union.  There are three classes of Booleans and associated types, which are axis-parallel (Manhattan), 45-degree restricted and arbitrary angle polygon operations.  This is done because it is significantly more efficient to process geometry data when assumptions about whether it is axis-parallel or restricted to 45-degree can be made.

-   * that edge is supposed to be solid or space.  Any incomplete polygon will have two active tails.  Active tails
-   * may be joined together to merge two incomplete polygons into a larger incomplete polygon.  If two active tails
-   * that are to be merged are the oppositve ends of the same incomplete polygon that indicates that the polygon
-   * has been closed and is complete.  The active tail keeps a pointer to the other active tail of its incomplete 
-   * polygon so that it is easy to check this condition.  These pointers are updated when active tails are joined.
-   * The active tail also keeps a list of pointers to active tail objects that serve as handles to closed holes.  In
-   * this way a hole can be associated to another incomplete polygon, which will eventually be its enclosing shell,
-   * or reassociate the hole to another incomplete polygon in the case that it become a hole itself.  Alternately,
-   * the active tail may add a filiment to stitch a hole into a shell and "fracture" the hole out of the interior
-   * of a polygon.  The active tail maintains a static output buffer to temporarily write polygon data to when
-   * it outputs a figure so that outputting a polygon does not require the allocation of a temporary buffer.  This
-   * static buffer should be destroyed whenever the program determines that it won't need it anymore and would prefer to
-   * release the memory it has allocated back to the system.

-// Transformation of Coordinate Systems
-// Enum meaning:
-// Select which direction_3d to change the positive direction of each
-// axis in the old coordinate system to map it to the new coordiante system.
-// The first direction_3d listed for each enum is the direction to map the
-// positive horizontal direction to.
-// The second direction_3d listed for each enum is the direction to map the
-// positive vertical direction to.
-// The third direction_3d listed for each enum is the direction to map the
-// positive proximal direction to.
-// The zero position bit (LSB) indicates whether the horizontal axis flips
-// when transformed.
-// The 1st postion bit indicates whether the vertical axis flips when 
-// transformed.
-// The 2nd position bit indicates whether the horizontal and vertical axis
-// swap positions when transformed.
-// Note that the first eight values are the complete set of 2D transforms.
-// The 3rd position bit indicates whether the proximal axis flips when
-// transformed.
-// The 4th position bit indicates whether the proximal and horizontal axis are
-// swapped when transformed.  It changes the meaning of the 2nd position bit
-// to mean that the horizontal and vertical axis are swapped in their new
-// positions, naturally.
-// The 5th position bit (MSB) indicates whether the proximal and vertical axis
-// are swapped when transformed.  It is mutually exclusive with the 4th postion
-// bit, making the maximum legal value 48 (decimal).  It similarly changes the
-// meaning of the 2nd position bit to mean that the horizontal and vertical are
-// swapped in their new positions.
