- TODO: added section for tasks done
- TODO: search tree optimization is done
- TODO: added idea of supporting other database formats in the same family
- jrb.h, jrb.c (jrb_find_or_insert): new function to look for a node and
to insert a new one if not found
- id.c (make_id): use jrb_find_or_insert to avoid looking up new nodes
twice
- TODO: report the improvement
This is a change of the underlying mechanism but it's not polished or
optimized yet. The compare functions haven't been updated, so they work
but produce compiler warnings because of type mismatches.
- Makefile (OBJS): added jrb.o
- id.h, id.c: use jrb instead of own dumb binary trees
- TODO: brag about the efficiency improvement
