The following changes have been applied to src and lib folders:
regex replace: ([^"_])NULL ⇒ \1nullptr (8968 chgs in src, 1153 in lib)
Manually find/change: (void \*) nullptr ⇒ nullptr (1 case)
regex find: ".*?nullptr.*?"
Manually ~14 cases back to "NULL" in src, ~2 in lib
regex finds a few false positive where nullptr appears between two
strings in a function call
- modified min spin names (removed oso from spin/cg and spin/lbfgs)
- modified associated option name (from spin_oso_cg to spin/cg, same for
lbfgs)
- modified .gitignore, doc pages, and examples accordingly
