IVGCVSW-3030 Refactor code and fix OptimizeSubgraphView

 * Refactored the Optimizer code for readibility, in view of
   upcoming changes
 * Rename one of the ISubgraphViewConverter interface methods to
   give it a more meaningful name
 * Improved the OptimizationViews class, added comments and
   useful funtion overloads
 * Fixed an error in the default implementationof the new
   OptimizeSubgraphView method in IBackendInternal
