Implementing Custom Analytics

i have a Analytics platform that i wrote in C++ for a different project; it works great and all the infrastructure is in place.
Now, i would like to reuse that work in UE4, and write a plugin that wraps the c++ classes (preferably exposing them as blueprint node since i am the only one on my team that understands C++.)
Problem is i don’t have any clue how to attack this; Are there any examples that i can look at or a place to start from?

p.s. i have looked at the plugin samples and i believe i can get the plugin portion working… i am more interested in creating the wrapper/shim to take my Analytics classes and being able to expose them in blueprint
