Instances of this class represent an attachment on the client. This is used with the AGSAttachmentManager. This class automatically saves the attachment data to a temporary file and pulls the data out from that temporary file when needed. Thus, it does not store actual attachment data in memory. The temporary file is cleaned up when the AGSAttachmentManager that is managing this attachment is cleared.
