csv output

This is the basic example, it shows how to encode columns for csv handler:

--handlers out-csv out=file.csv.gz columns=osm-id,id

But it says nothing about columns itself. You can find column keys here:

• https://github.com/kiselev-dv/gazetteer/blob/develop/Gazetteer/src/main/java/me/osm/gazetter/out/FeatureValueExctractorImpl.java
• https://github.com/kiselev-dv/gazetteer/blob/develop/Gazetteer/src/main/java/me/osm/gazetter/out/AddrRowValueExctractorImpl.java

The difference between AddrRowValueExctractorImpl and FeatureValueExctractorImpl is that one feature (building or poi or whatewer) may have more than one address. Columns in FeatureValueExctractorImpl are for the whole feature and AddrRowValueExctractorImpl for each address inside feature.

If feature contains more than one address, lets say 2 addresses, the output csv will has 2 rows, data from FeatureValueExctractorImpl will be the same, and data from AddrRowValueExctractorImpl will be specific.
