• Added option to import data manually as in xpose4 with manual_nm_import()
• Added indexing of variable and convenience functions to edit it: set_vars_type(), set_vars_label(), set_vars_units()

read_nm_files()

• Now imports multiple $PROB and sub-problems

Summary

• Added print() and summary() methods for xpdb
