Its done in the .onLoad function in zzz.R in zoo.  It seems that if
one re-installs zoo and then runs it that the .onLoad is not rerun.  I
would have thought it would reload the package and therefore .onLoad
would be run again..

Also there exists .onAttach but its not used by zoo.  Should the code
for as.Date.numeric be put in an .onAttach instead or in both .onLoad
and .onAttach?
