"""
To run with slash:
1. run pip install slash (may need to install C++ builds from Visual Studio website)
2. In the command prompt navigate to your project folder
3. then type--> slash run -vv -k tags:fibonacci ..
    -vv indicates the level of verbosity (how much stuff you want the test to spit out after running)
    -k is a way to select the tests you want to run.  This becomes much more important in large scale projects.
