New rule: file name and class name match

[prajapati93]

Guideline: File name and class name should be same.

Why it is recommended to keep the file name same as class name?

• Having the same name for the file and the class simplifies the process of locating the code for a specific class. This convenience arises from the fact that you can directly search for the file bearing the identical name as the class.
• When the file name and class name differ, there is a potential risk of opening an incorrect file when an individual is attempting to edit the code for a specific class. Such a situation may result in errors.

Solution: Always keep the file name same as class name.
For example: file name: trans_c.sv

 class trans_c;

 endclass : trans_c

Expected output:
