Flagship Profile: Construct Recursive Function to simulate a slow span

[kpujjigit]

Match the Profile Data capture in our Flask and Android Demos to demonstrate a recursive, out-of-hand function. The Flask demo has a getIterator() function to showcase this. The goal is to induce an artificial slowdown that's part of the checkout flow and showcases Profiling's capabilities.

Below is the recursively observed i our Flask demo by way of getIterator():

I have a PR ready producing this:

• Transaction with a product_processing span and corresponding Profile showing the recursive function

Hoping to get write access so I don't need to fork :)
