If you need a Java-like exception with a sort of "Throwable" cause to report the whole
stackTrace, you can use this class I wrote and I release under the LGPL GNU Lesser General Public
Liscence.
It looks more or less like the original PHP "Exception" but you might want to change the
formatting of the returned string in the two last functions. Enjoy :)
