// <synopsis>
// DataManInfo is a class to manipulate a datamanager info record and table
// descriptions.
// Often an existing table description and datamanager info record is used to
// construct a new table, but it might be necessary to change it somewhat.
// <ul>
// <li> Remove hypercolumn definitions from a table description. They are
// not needed anymore and can be a burden.
// <li> Replace non-writable storage managers (like LofarStMan) by a
// writable one.
// <li> Replace the deprecated TiledDataStMan by TiledShapeStMan.
// </ul>
//
// Such things might be necessary in a number
// </synopsis>

// Replace non-writable storage managers by the given storage manager
// (usually StandardStMan or IncrementalStMan).
// It is possible to specify the new data manager type to use.

// Set the data managers of the given column(s) to the given tiled storage
// manager (normally TiledShapeStMan or TiledColumnStMan).
// The columns are combined in a single storage manager, so the function
// has to be called multiple times if, say, one per column is needed.
// The columns already having a tiled storage manager are not changed.
