Bugfixes
- Fixed output messages when creating individual nodes.
- Fixed the problem that occurred when you wanted to save the generalized nodes file in a non-existing directory, where the program did not create the directory automatically. Now the program should create any parent directory as necessarily when saving generalized nodes.
Pending issues
The program still cannot load SHP files from a directory using wildcards like asterisks when running under Windows. For now, is necessary to add each file individually.
