Module a.error

Exception classes for the Aculab API.

Job termination reasons are also modelled as exceptions. This is stretching the concept 'exception' a little, because some are perfectly normal and to be expected.

But since exeptions due to an error may also occur, this seems better than to create a distinction between expected causes and unexpected ones - in particular because the distinction is arbitrary in some cases.

See StopIteration for a precedent.
