Provides following features:
* compile time typesafe callbacks (faster than run time checks)
* typesafty violations line number reports correctly with
template names (no tracing template failures into headers)
* no compiler extensions or meta compilers required
* proper handling of dynamic objects and signals
(deleted objects will not cause seg faults)
* extendable API at any level
Slot, Connection, Object, and Signal
* extensions do not require alteration of basic components
to allow use of extensions
* User definable marshallers
* provides headers for up to 7 arguments and 2 callback data
* M4 Macros for building templates with various numbers
of arguments and callback data
* Easily build support for templates with number of arguments
and callback data not defined in library headers
