Dynamic layout direction

Created by: ghost

can you add a $Direction variable in _variable.scss file to better supporting RTL layouting and text formating in bootstrap 4. i mean the layout of bootstrap template (RTL or LTR) can change simplify by changing the $Direction. somthing like this:

_anyfile.scss (like dropdown, forms, grid)

@if($Direction == 'ltr'){
      float:left;
}
@else{
     float:right;
}
