* Check a type for an equality operator

separate tests to determine if an object has a member operator
and/or a global operator for comparison tests
It isn't all that whacky as the required traits for testing for
members have been included in the standard library for C++17:

I use it in my production code, it is actually quite reasonable
for a library solution.
* Expansion of code for a script wrapper to a native function
(retrieve parameters and pass to native)
- C++ - Pre-C++11 is a mess but doable. Will focus on C++11,
which requires template parameter inference, compile time
number range generation, and calling a function with two dummy
instances of objects to allow the inference to happen.
Not sure what you mean by this. There have been improvements to
template arguments in all recent revisions of C++ so prepare for
comments from the audience.
