$tableSpec->resolve_dbic_colname( $fieldName, \%merge_join, $get_render_col )

Returns a value which can be added to DBIC's ->{attr}{select} in order to select the column.

$fieldName is the ExtJS column name to resolve. %merge_join is a in/out parameter which collects the total required joins for this query. $get_render_col is a boolean of whether this function should instead return the DBIC name of the render column.
