Initial start tests

[AnthonySinitsa]

I have updated the README slightly, I've put how to install requirements.txt for the dependencies and also added a testing section to know what command to run.

In LangTrans.py I have made 2 changes, it was erroring out on those lines due to incorrect arguments amount. However take those changes with a grain of salt.

I have also moved LangTrans.py into it's own folder for clarity, if you decide to not want it in it's own folder and want it in the root you will have to change the import locations inside of test_LangTrans.py
Must change from:
from LangTrans.LangTrans import 'functionName'
to
from LangTrans import 'functionName'

The testing file that I have added does not test all the functions that exist, this is just a starting point.

Having LangTrans as a single file without a folder is good for now. I've added unit tests for the functions, using unittest instead of pytest in FunctionTest.py . You folks can help me in enhancing these tests; some of them need improvement, and certain functions haven't been tested yet like loading YAML. Porting and improving the your tests would be helpful, particularly the commit 7f55de7
