A C++ exception class and macros with easy nested declaration and localisation
data.
The point of this system is to permits to easily add to exceptions instances
some informations about _where_ the exceptions are thrown.
To do so, it uses compilers macros that indicates the current function, file and
line (__FUNCTION__, __FILE__ and __LINE__ for g++) and merge those information
with the given description returned by the _what_ standard method.
Example:
`throw Existential_Observation( "Shit happens", E_INFOS );`
Additionaly, it permits a one-line declaration of new exceptions, derived from
existing ones.
Example:
`EXCEPTION(Exception, Existential_Observation );
EXCEPTION(Existential_Observation, Pastafarism_Observation );`
