The criteria for an apartment building is just anything tagged as a building
or landuse=residential

The Shard has an alias of 'London Bridge tower', my software trims these
endings from apartment building names to find more matches: house, apartments,
estate, and tower.

I might add 'building=train_station' as an exclusion for the apartment
building matching.

The matcher will be changed to say if there is an OSM object who's name
matches without trimming names, then it takes priority.

Thanks I'll investigate these. I'm going to add more debugging to the output,
so we can see the names that matched.
