This Fixes #358

Earlier the context API was used to toggle theme . I have used RECOIL js to to change the theme of the website .
This will enhance the loading speed of the website and will reduce the number of re rendering .
Will make this a more robust Client side rendering App .

I did not touched the ProgressBar code because of the following reasons :

• it is not being used at many places .
• using Recoil for it wouldn't make that big of a difference
  conclusion: it was not the case where you would use RECOIL .
