[dataimport] make eids_seq_range as massive store instance attribute again I changed it to a class attribute recently, but on further thought (and prompting from Adrien) it seems to make more sense as an instance attribute.

include *.py
include */*.py
recursive-include data *.gif *.png *.ico *.css *.js
recursive-include i18n *.po
recursive-include wdoc *
