Use Wrapper to avoid empty div's for grouping

After using wrapper instead of div, grouping ignored wrapper tag. 

created wrapper for ignoring grouping div, (for performance increase)

wrapper in app.js<Wrapper>...</Wrapper>

2. type : use empty wrapper <>....</>

3.type if empty tags wrapper wont work use below 

<React.Fragment> ....</React.Fragment>

Type 4:  import Fragment in react: then add tag <Fragment></Fragment>

Note
With Type 2,3,4  no need of using type 1 wrapper creation, 
Type 2,3,4 are inbuild, 
Type 1 is manually created for understanding, how wrapper works.
