+ 
+   Title   : coordinate_policy
+   Usage   : $policy = $location->coordinate_policy();
+             $location->coordinate_policy($mypolicy); # set may not be possible
+   Function: Get the coordinate computing policy employed by this object.
+ 
+             See L<Bio::Location::CoordinatePolicyI> for documentation
+             about the policy object and its use.
+ 
+             The interface *does not* require implementing classes to
+             accept setting of a different policy. The implementation
+             provided here does, however, allow to do so.
+ 
+             Implementors of this interface are expected to initialize
+             every new instance with a
+             L<Bio::Location::CoordinatePolicyI> object. The
+             implementation provided here will return a default policy
+             object if none has been set yet. To change this default
+             policy object call this method as a class method with an
+             appropriate argument. Note that in this case only
+             subsequently created Location objects will be affected.
+ 
+   Returns : A L<Bio::Location::CoordinatePolicyI> implementing object.
+   Args    : On set, a L<Bio::Location::CoordinatePolicyI> implementing object.
+ 
+ See L<Bio::Location::CoordinatePolicyI> for more information
