%% Usage: \usepackage[options]{hep}
%%   where "options" are any of: fd     --- includes feynmf and axodraw for making Feynman diagrams
%%                               layout --- some nice layout tweaks like booktabs, setspace and fancyhdr
%%                               hyper  --- include hyperref with some sensible default options
%%                               float  --- include morefloats and afterpage for extra float handling flexibility
%%                               all    --- all of the above
