@SYMTestStatus            Implemented

@SYMTestType              CT

@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.
