Based on Mislav's gist and vim-tmux-navigator.

Since tmux hosts vim I disliked that I had to install a vim plugin for this. Instead I think it's cleaner to control vim from tmux.

My actual goal was to achive the following behaviour though (I have a default setup similar to the one Mislav shows in the gist. Two vertically split tmux panes, where the left one hosts vim, which has two vertically split windows):

On the leftmost window in vim: when I hit C-h (do not wrap to the rightmost tmux pane, but) zoom the left tmux pane.
On the rightmost tmux pane: when I hit C-l (do not wrap to the leftmost tmux pane, but) zoom the right tmux pane.
All other navigation: work as given in Mislav's gist
