23  \class CGridTransformation
24  This class is an interface for all transformations to interact with the rest of XIOS.
25The class, firstly, tries to get all information relating to requested transformations by retrieving directly from grid.
26Then with all these information, all necessary transformations will be created by generic class \class CGenericAlgorithmTransformation.
27Because there are information exchange among clients to accomplish the transformations (e.g: some index need retrieving from other clients),
28this class uses class \class CTransformationMapping to fulfill this demand.
29For each transformation, a new temporary grid source is created.
30For a consequential transformations (e.g: inversing -> zoom -> inversing -> ...),
31the grid destination of current transformation will be grid source of the next transformation
