"com\intuit\..." prefixes on class types

[themightychris]

What's with all the properties being declared with types like com\intuit\schema\finance\v3\IPPReferenceType:

https://github.com/intuit/QuickBooks-V3-PHP-SDK/blob/master/src/Data/IPPSalesTransaction.php#L71

When the namespace for IPPReferenceType is QuickBooksOnline\API\Data:

https://github.com/intuit/QuickBooks-V3-PHP-SDK/blob/master/src/Data/IPPReferenceType.php

This makes it impossible for a project setting these properties to pass static analysis without tons of exceptions
