Subject: teach flattenergrid/store a new trick called softFieldReMap,
X-Git-Url: https://old-git.evergreen-ils.org/?a=commitdiff_plain;h=481016a23a1350bc940156c85dc5d93a1ec363cc;p=evergreen%2Fequinox.git

teach flattenergrid/store a new trick called softFieldReMap,

which enables to use one column to sort another. This is perfect for
sorting call numbers by call number sortkey, which we're now doing.
