1 - Create app with 7 languages
2 - Allow user to select language - save the selected language to a global variable
3 - Display menu based on whatever language the global variable specifies
4 - Save global variable to localstorage "languageSelection" key
5 - On start of layout, if "languageSelection" key exists in localstorage, set global variable to "languageSelection"
