@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.
