Changes

Summary

1. trivial isEmpty
2. exception changes with new codes
3. bug https://sourceforge.net/p/autoplot/bugs/2613/: refactor to support virtual variable for DEPEND_1, where array_slice was used.
4. always report the lengths of the variable, not the lengths of the DEPEND_1, in the first line. Clarify inconsistent DEPEND_i warnings.
5. increase the default connect timeout as the NASA firewall can cause long delays.
