// Macro to merge the tag files from an ESD collection.
// The tag files are stored according to the value set in the SetStorage method
// Use Case : 
//          SetStorage(0) --> store the tgs locally
//          SetStorage(1) --> store the tgs in the grid
//          else the program will abort!!!                                    
//                                             
// As a final step the user can create a single merged tag file.
