Subject: Move the code to create accessors out of ColumnCase and into ColumnGroups.
X-Git-Url: http://git.shadowcat.co.uk/gitweb/gitweb.cgi?a=commitdiff_plain;h=8da46543004ecb546d27b1cc40450d7160e8178f;p=dbsrgits%2FDBIx-Class-Historic.git

Move the code to create accessors out of ColumnCase and into ColumnGroups.
This allows one to remove ColumnCase without effecting other features.
