@bharathkkb , I was checking the issues with Amanda and we notice that we also have this issue #60 that asks for remove the simple_example. Do you think that we should remove the simples_exemple or add it to the tests?

[bharathkkb]

@LuizSDCit we can keep the simple example as it is no longer from the cookie cutter template. We can add the tests in a follow up PR

minor nit; great updates!
