read: read the contents of the FileBlackBox
@self: this FileBlackBox instance
This function is callable multiple times, and if it cannot
succede on a given call, it returns None. It does not
cache returns information in the normal sense, unless the data
is not dynamic. And it does not keep a reference to the
AdmContext it returns.
It also sets the serial of the returned context to the modify
time of the file.

write: write the contents of the FileBlackBox
@self: this FileBlackBox instance
This function is callable multiple times. It writes a
Context out to the file the FileBlackBox is initialized with.
It returns 0 on failure, and a non-zero, positive integer
on success.
