The repository for the assignment is public and Github does not allow the creation of private forks for public repositories.

The correct way of creating a private frok by duplicating the repo is documented here.

For this assignment the commands are:

1. Create a bare clone of the repository. (This is temporary and will be removed so just do it wherever.)

git clone --bare git@github.com:usi-systems/easytrace.git

Life Cycle Comparsion of Ember and React

React Hook	Ember Hook	Server?	Initial Render?	Rerender?	Purpose
componentWillMount	init	Yes	Yes	No	Set initial component state without triggering re-render
componentDidMount	didInsertElement	No	Yes	No	Provides opportunity for manual DOM manipulation
componentWillReceiveProps	willReceiveAttrs	No	No	Yes	React to changes in component attributes, so that setState can be invoked before render
shouldComponentUpdate	Maybe N/A	No	No	Yes	Gives a component an opportunity to reject downstream revalidation
componentWillUpdate	willUpdate	No	No	Yes	Invoked before a template is re-rendered to give the component an opportunity to inspect the DOM before updates have been applied (example)
componentDidUpdate	didUpdate	No	No	Yes	Invoked after a template is r

Installing a Gem on Heroku from a Private GitHub Repo

Sometimes you want to use a gem on Heroku that is in a private repository on GitHub.
