DELETE AN INDEXEDDB OBJECT STORE

You can delete an entire object store using the same basic code to create one, within a setVersion() request, using deleteObjectStore() :

function deleteObjectStore() {
   var request = db.setVersion('1.0');
   request.onsuccess = function(event) {
     db.deleteObjectStore(objectStore);
   };
   request.onerror = function(event) {...};
 }

The purpose of this is to be able to store multiple versions of data within the same object store within the same database.
