A set of simple zsh functions that wrap cd for quick access.
Creates a shortcut function which changes directory to paths under <path>,
including zsh path completion.
Example usage:
# Typically defined by your .zshrc:
~$ cdhelper src ~/src
# starting in $HOME
~$ src
# now in ~/src
~/src$ src foobar
# now in ~/src/foobar
~/src/foobar$
Invoking completion on wt with no arguments will show name and branch info
about all worktrees associated with the current git repository. Otherwise it
functions much like cdhelper defined functions above, e.g. to quickly cd into
a subdirectory of another worktree.
