Question: One of the inputs into cuOpt is the cost matrix, which is a n x n matrix showing the pairwise cost to travel from one point to another. Can we clarify how the current cost matrix is evaluated? Would the cost simply be the Euclidean distance between each point?

`euclidean distance`

/`cost of fuel to travel`

/`a function of time`

. cuOpt would just add these as it visits point to point. So it is up-to user to define what is cost.
