Gustavo Jose de Sousa c7eb46fae2 AP_Math: AP_GeodesicGrid: optimize _from_neighbor_umbrella() 
This is the second optimization. With that we don't have to iterate over the
umbrella's components.

The table below summarizes the mean CPU time in ns from the brenchmark results
on an Intel(R) Core(TM) i7-3520M CPU @ 2.90GHz processor:

       | Naive implementation | First Optimization | Second Optimization

Min.   |                 26.0 |              28.00 |                26.0
1st Qu.|                 78.0 |              48.75 |                39.0
