Add Unit Testing Framework

[avislash]

I'd like to incorporate the GTest Unit Testing Framework so we have repeatable and automated tests that can be used for regression testing and validation as updates to the SDK are made. My thought is to port the existing example.cpp file into a series of unit tests. that can be expanded upon later.

Please have a look at Algorand SDK Testing repo:
https://github.com/algorand/algorand-sdk-testing

Perhaps you can integrate with this framework.

This is a good suggestion and I wasn't aware something like this already existed. I'll investigate and comment on how feasible it is for me to take this approach.

@ryanRfox I took a look at the Pickle a few months back when you recommended it. It looks like a good approach to take and the C++ version of Pickle actually uses GTest under the hood. @jannotti what are your thoughts?
