Changes for version 0.08
- New BUILD code that calls map() xor str2map() for easier object setup. next* methods return array reference instead of list to make them more like other methods. New unconnected() and values() methods. Learn more about normalize_costs (it does not do diagonals). Add next_m to set what next method to call instead of that being an argument to various next_* methods. New dimap_with() and next_with() for weights in combination with other map objects. And to_tsv() to help debug those.
Modules
a numeric grid of weights plus some related functions
