CAVU conditions

The CIGI interface allows to force CAVU conditions for lower visibility values.  This can be useful for existing interfaces that have limited control over the maximum visibility.

ForceCavuRange 300000.0  - This values is in meters and determines at what threshold the IG will push the visibility out to max range.  If the current interface can only send up to 80000m, then setting this to 80000.0 will force clear skies.
