USER STORY: Finalize flow & routing for the app

[blahosyl]

As a Developer,

I want to implement an intuitive and smooth user flow between different parts of the app,

so that user experience is as good as possible

Acceptance Criteria

1. User journey with possible paths is documented

   • Pages available to Logged-out Users:
   • Landing (default)
   • Signin
   • Signup
   • Pages available to Logged-in Users:
   • Tasks
     • TaskKanban (default)
     • TaskList
     • TaskDetail
     • TaskCreate
     • TaskEdit
     • TaskDelete (implemented with modal on TaskKanban/List/Detail)
   • Profiles/Users
     • ProfileList/Teammates
     • ProfileDetail
     • ProfileEdit
     • Username Edit
     • Password Edit

2. Routing & redirecting implemented accordingly

Tasks

• [x] implement routing & redirecting accordingly
  • [x] redirect Logged-in Users from landing page in Landing
  • [x] redirect Logged-out Users from TaskTab & Kanban pages (only need to set redirect in TaskTabs, as TaskKanban is called as its child)
  • [x] redirect Logged-in Users from Team page in ProfileList (needs to be converted into a function OR the Landing component should be imported as the else case of the currently implemented logic of only showing the contents if there is a currentUser)
  • [x] redirect Logged-in Users from ProfileDetail page in ProfileList
• [x] remove superfluous routes from App.js
• [x] make Kanban Navbar link active on home page
