Add and use a placeholder for checkIsDocumentPublic
We should somehow decide whether a document is publically viewable.
This should of course be dependant on what the document is, e.g. the
FAQ of a program should be allow(), whereas a student's application
should be checkIsMentor().

hashlib module containing both hash algorithms. Here, we provide a common
interface to the md5 and sha constructors, preferring the hashlib module when
available.
