One nmap to rule them all

[soerenwolfers]

Can I use tcomment to create a normal mode map, let's say to ', that does:

• On a not commented line: Immediately comment out the line
• On a commented line:
  • If the line doesn't have adjacent commented lines: immediately uncomment the line
  • If the line does have adjacent commented lines
    • Uncomment all of them if ' is pressed again within a time limit (set timeout)
    • Uncomment the current line if ' is not pressed again within a time limit (or any other key is pressed)
