/*
Note: There are two contexts for handling errors.
A static V8ErrorHandler is used in not overloaded methods.
For overloaded methods the throwing type checking mechanism is used
during dispatching. As V8 exceptions can not be resetted properly
the trick is to use a dynamic ErrorHandler with same local name as the global
one.
- See defintion of SWIG_Error above.
- See code templates 'JS_function_dispatcher', 'JS_functionwrapper_overload',
and 'JS_function_dispatch_case' in javascriptcode.swg
