Problem 490. Fastest shortest-path-finder in the west

Ok, cody was friendly enough to still allow easy hacks to the scoring function (I am pretty sure they are allowing this back doors on purpose, so thanks matlab team for still permitting this sort of time-scored problems!), so this problem should be back to scoring based on time instead of length. Rescoring now...

and @fel, it seems your 'vectorized' solution outperforms my 'matrixized' solution for large and relatively dense connectivity matrices, yet it still performs a bit slower for smaller or for more sparsely connected networks...

thank you for making this kind of problems! i was a bit tired of the minimum size scoring. Good job!
