A utility based on tmux hooks in order to track time attached to each session

2. Run cargo build --release 3 .Move ./target/release/tmux-time-tracker into you $PATH
3. Add the following to your tmux.conf: bash set-hook -g client-attached 'run-shell "output=$(tmux-time-tracker geth #{session_name}); tmux-time-tracker attach #{session_name}; tmux display-message \"Total time: \$output\""' set-hook -g client-detached 'run-shell "tmux-time-tracker detach"' set-hook client-session-changed 'run-shell "tmux-time-tracker detach; tmux-time-tracker attach #{session_name}; output=$(tmux-time-tracker geth #{session_name}); tmux display-message \"Total time: \$output\""'

WARNING: does not work correctly if you attach to the same tmux instance from multiple clients
