/** @file
@author Robert Kloefkorn
@brief Provides check for implementation of interface methods when using
static polymorphism, i.e. the Barton-Nackman trick.
Use by invoking CHECK_INTERFACE_IMPLEMENTATION(asImp().methodToCheck())
and for template methods double (
CHECK_INTERFACE_IMPLEMENTATION((asImp().template methodToCheck<param> ())).
