/** \class RAMDrivenAdaptativeStreamingManager
* \brief This class computes the divisions needed to stream an image
* according to the input image tiling scheme and a user-defined
* available RAM.
*
* This streaming manager uses the TileHint from the
* MetaDataDictionary to find out the tiling sheme of the input file
* if available.
*
* You can use SetAvailableRAMInMB to set the available RAM. An
* estimation of the pipeline memory print will be done, and the
* number of divisions will then be computed to fit the available RAM.
