Feature: user onboarding (tutorial)

[JasonBarahan]

New users are given the option to partake in a tutorial for onboarding.

An option to skip is provided for users who have used the application before.

This will hopefully make our application more accessible to users.

Although this is a good feature to implement, and we might be looking to do this in the future, we will be prioritizing other use cases first
