Tabbed implements a tab container. There are also different themes for the tabs.
### Usage
You should bind these functions to keys in order to use the tabbed module effectively:
```lua
bling.module.tabbed.pick() -- picks a client with your cursor to add to the tabbing group
bling.module.tabbed.pop() -- removes the focused client from the tabbing group
bling.module.tabbed.iter() -- iterates through the currently focused tabbing group
bling.module.tabbed.pick_with_dmenu() -- picks a client with a dmenu application (defaults to rofi, other options can be set with a string parameter like "dmenu")
