Code style update

[kavimaluskam]

I am not sure how do you think about this @emkay Anyway there are some suggestion below:

1. use import over require
2. use class extends React.Component over React.createClass
3. separate the file over few components

1. use import over require

My preference would be to use require. I don't really see any benefit in using import. Happy to concede on this point though because it doesn't matter a ton to me either way.

2. use class extends React.Component over React.createClass

Sure! I have grown to really like class.

3. separate the file over few components
