did some debugging but still needs more
parses sort of make sense
none
terrible terrible parsing performance must fix
risky rewrite of some key functions but seems to work
about to add more grammar
more code visibility
caching works and results in big speedup
added spatial data structure
made search regions code clearer but code seems slower
parsing fractions sort of works
start commit
getting reasonable results and infrastructure seems ok
code is broken but some good ideas
things essentially working and code is cleaner
best performance including fractions yet
