Add restart option #22
Description
Feature request. Especially relevant for HPC computing.
It should be possible to restart the dtw cost matrix computation after a crash/exit. This will become relevant if we try to scale up the programme to work on a computational cluster.
A possible way of implementing this would be to gradually fill the dtw cost matrix and using a token value (-1?) for pairwise calculations that have not yet been made. Then one can supply the program with an optional --restart flag that would make sure the programme first checks for any already available cost matrix before deciding what pairwise calculations to launch.
