/*++

Routine Description:

    Collect cover page information into the fields of a newly allocated COVERPAGEFIELDS structure. 
	Fills sender information using the client registry. The following fields are filled:
		SdrName
		SdrCompany
		SdrAddress
		SdrTitle
		SdrDepartment
		SdrOfficeLocation
		SdrHomePhone
		SdrOfficePhone
		SdrFaxNumber
		SdrEmail
	NumberOfPages = pageCount
	TimeSent = formatted date/time string of the current time (calculated at this point)

Arguments:

    pageCount - Total number of pages (including cover pages)

Return Value:

    Pointer to a newly allocated COVERPAGEFIELDS structure, NULL if there is an error.
	It is up to the caller to free this structure using FreeCoverPageFields() which takes
	care of freeing the fields as well.
