This revision improves upon changes made to the `all_sky2pix` in r31122 and r31123 that address issues described in ticket #1121 and ticket #1122, by implementing a more robust handling of the divergent solutions. The new parameter `detect_divergence` will allow to detect divergent solutions at each iteration. Now, even if `adaptive` is set to `False`, assuming `detect_divergence` is `True`, when divergent solutions are detected `all_sky2pix` will automatically switch from the highly efficient fully vectorized algorithm to a less efficient (~30%) (still vectorized) but adaptive algorithm.
Updated comments and examples to `all_sky2pix` to reflect the changes.
