Number of pages in the document being uploaded.

PageCount # get and set (UploadDocumentOptions)
The number of pages in the document being uploaded. The default value is 0.
This value is optional and setting it depends on the application's requirement.
This value is just a hint for the factory when it first tries to load the document. If the value of PageCount is 0 or a wrong value, then it will be overridden by the factory and the real number of pages obtained from the document data.
Note that the original value set here in PageCount will be returned by DocumentFactory.GetDocumentCacheInfo if called prior to the factory loading the document.
