PyAstronomy exceptions and warnings

Occasionally, it is necessary to raise an exception or, at least, show a warning. In the ideal case, this should inform the user exactly about what went wrong (if anything) and provide her/him with a solution to the problem.

PyA contains an exception template, which is the base class of all more specialized PyA exceptions. The template defines a set of information, which can be given to support the user to solve the problem. An exception class may also be used to show a warning by handing it to the warn function.
