//Description: Contains the MyClasses.MetaViewWrappers.ViewSystemSelector class,
//  which is used to determine whether the Virindi View Service is enabled.
//  As with all the VVS wrappers, the VVS_REFERENCED compilation symbol must be
//  defined for the VVS code to be compiled. Otherwise, only Decal views are used.
//
//References required:
//  VirindiViewService (if VVS_REFERENCED is defined)
//  Decal.Adapter
//  Decal.Interop.Core
