Column :: id - Column identifier

Usually, columns are accessed via position or name. When creating columns, however, within the application, the column identifier will be returned and might be used for accessing the column.

When inheriting a column from an upper region, the column identifier is the one from the column in the upper region.
Return value:  Column identifier ( int64  )

The column identifier is either the resource identity for the column definition (in case the column has been created from an external resource) or the internal column identifier returned from the ControlContext::addColumn() function.
