* Indent is used to control indentation during the chaining print
* process. This way nested objects can correctly indent themselves.
* This class works with the print methods defined in Object (i.e.,
* the public method Print() and the protected methods PrintSelf(),
* PrintHeader(), and PrintTrailer().
*
* \ingroup OSSystemObjects
