draft zsh completion loader
So what I though should be a single
fpath=($fpath $some_lhcb_dir)
turned out needs to be
fpath=($fpath $some_lhcb_dir)
compinit
except on the zsh users mailing list they advised against this (and this would even fail for me on the online cluster for $reasons) so here's a reimplementation of compinit :/ inspired by the zplugin readme.
Mostly untested …
