+@SYMTestCaseDesc          Tests the performance of a bulk delete operation on a corporate-profile 
+						  database of 1000 contacts.
+						  
+@SYMTestActions           Measures the time taken to perform a bulk delete on the contacts database
+						  by passing a CContactIdArray to:
+						  -- CContactDatabase::DeleteContactsL()
+
+@SYMTestExpectedResults   Test case will run without leaving and will output timing information.
