Add some option to report functions with template as single function in generated (html) reports

template <class type> type sum( type x, type y) { return x+y; } int main() { auto result1 = sum(0u,1u); auto result2 = sum(0.0f,1.0f); auto result3 = sum(0.0,1.0); exit(0); } 

So instead of having a coverage report with three (3) functions of sum, actually report with single sum function would be preferred.
