Force Only one instance of Gnome Terminal

I use tmux and I prefer only one instance of gnome-terminal open all the time. With the following script I achieve:

1. Open a new terminal if there is no any terminal opened
2. If terminal is already opened it will bring that terminal to the active workspace and focuses it
3. If you execute script sitting on the active terminal, it minimizes the terminal
