Migrating FAQ

Code that relied on the prior (index-based handles) MDL C Container API (mdlCntr); wrt: List, Map and Multimaps; where appropriate can upgrade code to use native C++ std library list and map functionality.
Code specific to the mdlRaster API use of mdlCntr should consider:

1. Upgrade code to use Raster C++ API classes and interfaces: DgnRaster*, Raster*, IRaster*
2. Upgrade mdlRaster API signatures accordingly to use:
   • mdlRaster_systemAllRasterContainerByModelGet  use DgnRasterVectorR
   • mdlRaster_fileFormat* use: RasterBlockTypeCollectionR, RasterColorModeCollectionR, RasterCompressionTypeCollectionR and RasterFileFormatCollectionR
