The app does not currently have a Journeyers page with the participants' info.

Issue Number: #7

What is the new behavior?

A table with the badge( picture and full name), Github username, Twitter username, and a progress bar of the challenge.
the table is

• Lazily loaded ( 10 users at a time) - wrapping around at the end of the users' list
• Sortable by name, usernames and progress
• includes a tool tip to show the real number of days, since the progress bar only registers until 100 days (100%)

Does this introduce a breaking change?

• Yes
• No

Other information

There is an issue to be added: ProfileBadge component needs a feature to customize the 'justify' option for the picture and the the name inside the badge.
