GF Model
+ Apply the Eric's Baker gradient formula.
+ Apply GF varying corrections for each compartiment.
+ B?hlmann 100/100 == Gradient factor 100/100.
+ Compute stop with gradient at current depth (not GF_low)
+ Add assert() on visual platform.
+ Overflow stop into the next bin at same depth.
+ debug last deco depth in range 3m..6m.
