//  plCommonObjLib - Base class for a library of objects that are stored    //
//                   in common pages (for now, that means Textures or       //
//                   BuiltIn pages).                                        //
//                                                                          //
//// How To Use //////////////////////////////////////////////////////////////
//                                                                          //
//  Derive from this class and override the IsInteresting function to       //
//  filter out which objects you're interested in. Then, create an object   //
//  of this type (static is fine) before the export process begins.         //
//                                                                          //
//  Then, when you are going to create an object in a common page, call     //
//  this lib to see if the object is already created. If so, it'll already  //
//  be loaded and ready to go, and you shouldn't create another one. Of     //
//  course, you always have the option of deleting it and creating another. //
//                                                                          //
//  The single biggest limitation is that objects in common pages can NOT   //
//  have ANY refs to ANY other objects in ANY other page. Otherwise, their  //
//  refs will get completely screwed up at export time. So don't do it!!!   //
//                                                                          //
