#17 Re-organize folders and minor fix for unit test cases

[ats0stv]

Organized the modules as planned

• lexis is now first class
• io is renamed to inputouput to not conflict with python io and is now first class
• reorganized the imports with iSort For those interested

  find ./code -type f -regex ".*\.py" | xargs -I{} isort {}

Autopep8 format - JFYI

find ./code -type f -regex ".*\.py" | xargs -I{} autopep8 --in-place --aggressive --aggressive {}

Fixed test case relative paths Now from the code folder, all tests can be run using python -m unittest -v Output is as follows

python -m unittest -v
