Feature Request: Reused Classname/Html name throws errors

[NKesar75]

Hi, I looked through all the feature request (open and closed) and did not see the issue being asked.

The Feature Request is so Scss will look through all the files to see if the class name or HTML selector has been called before in at least one different SCSS file and if so it will throw a warning/error in the terminal to inform the user the name has been used so they might need to merge them/check it so they can check it and do the appropriate response of either editing/removing or refactoring the SCSS or simply adding a disable and reenable. It would help track down SCSS bugs and help make sure to make reusable SCSS that will help keep code clean and modular.
