[cdrani]

Implementation:

1. Setup husky: https://typicode.github.io/husky/get-started.html
2. Install prettier as dev dependency
3. Add .prettierrc file with the below configurations.

   {
   	"semi": false,
   	"tabWidth": 4,
       "printWidth": 100,
       "singleQuote": true,
       "trailingComma": "none",
       "bracketSameLine": false,
   }

4. Add dist and node_modules to .prettierignore file
5. Run prettier on all files.

@sstephanyy: This might be an even better first issue. Let me know if you want to claim this one instead. I have also updated the contributing file with steps for local development.
