* Implements llGroundSlope, llGroundNormal and llGroundContour in LSL_Api.cs - these functions are orthogonal to each other and the core implementation is in GroundSlope. 

* Please note that this implementation has not been mathematically verified to be correct-as-described, it is probable that this implementation may produce differing results to Linden Lab. Testing (and test data) would be appreciated.
