@SYMComponent             app-engines_cntmodel
@SYMAuthor                Simon Mellor, JamesCl
@SYMTestStatus            Implemented
@SYMTestType              CT

@SYMTestCaseDesc          Tests the performance of opening a corporate-profile database of 
						  1000 contacts, creating a remote view and retrieving some contacts.

@SYMTestActions           Measures the time taken to:
						  -- Open the database file with CContactDatabase::OpenL().
						  -- Create a RContactViewSortOrder and pass it to CContactRemoteView::NewL() 
						     to create a new remote view.
						  -- Retrieve contacts from the remote view using CContactRemoteView::ContactAtL().

@SYMTestExpectedResults   Test cases will run without leaving and will output timing information.
